Jeremiah 17:9

Clarke's Commentary

Verse Jeremiah 17:9. The heart is deceitful — עקב הלב akob halleb, "the heart is supplanting - tortuous - full of windings - insidious;" lying ever at the catch; striving to avail itself of every favourable circumstance to gratify its propensities to pride, ambition, evil desire, and corruption of all kinds.

And desperately wicked — ואנש הוא veanush hu, and is wretched, or feeble; distressed beyond all things, in consequence of the wickedness that is in it. I am quite of Mr. Parkhurst's opinion, that this word is here badly translated as אנש anash is never used in Scripture to denote wickedness of any kind. My old MS. Bible translates thus: - Schrewid is the herte of a man: and unserchable: who schal knowen it?

Who can know it? — It even hides itself from itself; so that its owner does not know it. A corrupt heart is the worst enemy the fallen creature can have; it is full of evil devices, - of deceit, of folly, and abomination, and its owner knows not what is in him till it boils over, and is often past remedy before the evil is perceived. Therefore trust not in man, whose purposes are continually changing, and who is actuated only by motives of self-interest.

Bridgeway Bible Commentary

Wrong attitudes and their outcome (17:1-13)

Baal worship has become so much a part of the people’s everyday lives that God sees it as engraved on their hearts. It is so widely practised in Judah that it cannot be removed from the land unless the people themselves are removed (17:1-4). Those who ignore God and trust in themselves are likened to a useless stunted bush that tries to grow in barren ground. Those who trust in God are likened to a healthy green tree that flourishes in well-watered fertile soil (5-8).
Because of the deceitfulness of the human heart, people may not understand their own actions and motives. Only God knows the hidden attitudes of their hearts, and he treats people accordingly (9-10). Those who gain riches by dishonest methods are also deceiving themselves. They will one day lose their riches, just as a bird that hatches eggs stolen from another bird’s nest will lose the young birds when they grow and fly away (11). The only security in life is with the eternal God, whose presence is symbolized in the temple. But even the temple will not save those who turn away from him. The nation’s hope is in a person, not a building (12-13).

Coffman's Commentaries on the Bible

"The heart is deceitful above all things, and it is exceedingly corrupt: who can know it? I, Jehovah, search the mind, I try the heart, even to give every man according to his ways, according to the fruit of his doings. As the partridge that sitteth on eggs which she hath not laid, so is he that getteth riches and not by right; in the midst of his days they shall leave him, and at his end he shall be a fool."

The question that surfaces here is, if the one who serves God fares so much better in this life than the unrighteous person, why do men then trust the arm of flesh? Barnes attempted an answer to this, saying, "Because man's deceitful heart is incapable of seeing things in a straight-forward manner; it is full of shrewd guile."Barnes' Notes, p. 192.

Our heart's a soil that breeds
The sweetest flowers or vilest weeds,
Flowers lovely as the morning light,
Or weeds as deadly as the aconite.W. Harvey Jellie, Jeremiah, in Preacher's Complete Homiletic Commentary (New York: Funk and Wagnalls Company), p. 385.

The mention here in Jeremiah 17:11 of a partridge setting upon eggs she did not lay derived from, "A popular belief of antiquity, which Jeremiah used to illustrate the truth that riches unlawfully acquired are a precarious possession."J. R. Dummelow's Commentary, p. 467. Translators usually render this as a statement that the eggs would not hatch; but John Bright in the Anchor Bible rendered it "Like a partridge hatching eggs that it laid not."18, p. 115.

The personal experience of this writer and his brother Robert verifies the truth that hatching "strange eggs" can be a terrible mistake for the hatcher!. Robert had a pet hen, named Bob White; we found a hawk's nest and put two of the eggs under Bob White when the hen was setting, and one of the hawk eggs hatched. Our father wanted to kill it, but we insisted on keeping it. Then, one day when we came home from church the young hawk was sitting on the gate post with Bob White's feathers scattered all around! He had eaten his own mother!

The old proverb about the partridge's hatching eggs that she had not laid is not supposed to be true to natural history; but that did not prevent Jeremiah's use of it as an illustration. There is no necessity to charge Jeremiah with believing the saying. Besides that, since the species of bird is not clearly identifiable, there might have been some bird, unknown to us now, of which the old saying was altogether true.

In fact, there was a Dr. Blayney, who thought that the bird here was not a partridge at all; and he translated the passage: "As the kore that hatcheth what it does not lay, So is he that getteth riches, and not according to right."Adam Clarke's Commentary on the Bible (London: T. Mason and G. Lane, 1837), p. 302.

Barnes' Notes on the Whole Bible

In the rest of the prophecy Jeremiah dwells upon the moral faults which had led to Judah’s ruin.

Jeremiah 17:6

Like the heath - Or, “like a destitute man” Psalms 102:17. The verbs “he shall see” (or fear) and “shall inhabit” plainly show that a man is here meant and not a plant.

Jeremiah 17:8

The river - Or, “water-course” Isaiah 30:25, made for purposes of irrigation.

Shall not see - Or, “shall not fear Jeremiah 17:6.” God’s people feel trouble as much as other people, but they do not fear it because they know

(1) that it is for their good, and

(2) that God will give them strength to bear it.

Jeremiah 17:9

The train of thought is apparently this: If the man is so blessed Jeremiah 17:7-8 who trusts in Yahweh, what is the reason why men so generally “make flesh their arm”? And the answer is: Because man’s heart is incapable of seeing things in a straightforward manner, but is full of shrewd guile, and ever seeking to overreach others.

Desperately wicked - Rather, mortally sick.

Jeremiah 17:10

The answer to the question, “who can know it?” To himself a man’s heart is an inscrutable mystery: God alone can fathom it.

Ways - Rather, way, his course of life. The “and” must be omitted, for the last clause explains what is meant “by man’s way,” when he comes before God for judgment. It is “the fruit,” the final result “of his doings, i. e., his real character as formed by the acts and habits of his life.

Jeremiah 17:11

Rather, “As the partridge hath gathered eggs which it laid not, so ...” The general sense is: the covetous man is as sure to reap finally disappointment only as is the partridge which piles up eggs not of her own laying, and is unable to hatch them.

A fool - A Nabal. See 1 Samuel 25:25.

Jeremiah 17:12, Jeremiah 17:13

Or, “Thou throne ... thou place ... thou hope ... Yahweh! All that forsake Thee etc.” The prophet concludes his prediction with the expression of his own trust in Yahweh, and confidence that the divine justice will finally be vindicated by the punishment of the wicked. The “throne of glory” is equivalent to Him who is enthroned in glory.

Jeremiah 17:13

Shall be written in the earth - i. e., their names shall quickly disappear, unlike those graven in the rock forever Job 19:24. A board covered with sand is used in the East to this day in schools for giving lessons in writing: but writing inscribed on such materials is intended to be immediately obliterated. Equally fleeting is the existence of those who forsake God. “All men are written somewhere, the saints in heaven, but sinners upon earth” (Origen).

Jeremiah 17:15

This taunt shows that this prophecy was written before any very signal fulfillment of Jeremiah’s words had taken place, and prior therefore to the capture of Jerusalem at the close of Jehoiakim’s life. “Now” means “I pray,” and is ironical.

Jeremiah 17:16

I have not hastened from - i. e., I have not sought to escape from.

A pastor to follow thee - Rather, “a shepherd after Thee.” “Shepherd” means “ruler, magistrate” (Jeremiah 2:8 note), and belongs to the prophet not as a teacher, but as one invested with authority by God to guide and direct the political course of the nation. So Yahweh guides His people Psalms 23:1-2, and the prophet does so “after Him,” following obediently His instructions.

The woeful day - literally, “the day of mortal sickness:” the day on which Jerusalem was to be destroyed, and the temple burned.

Right - Omit the word. What Jeremiah asserts is that he spake as in God’s presence. They were no words of his own, but had the authority of Him before whom he stood. Compare Jeremiah 15:19.

Jeremiah 17:17

A terror - Rather, “a cause of dismay,” or consternation Jeremiah 1:17. By not fulfilling Jeremiah’s prediction God Himself seemed to put him to shame.

Jeremiah 17:18

Confounded - Put to shame.

Destroy them ... - Rather, break them with a double breaking: a twofold punishment, the first their general share in the miseries attendant upon their country’s fall; the second, a special punishment for their sin in persecuting and mocking God’s prophet.

Calvin's Commentary on the Bible

What is taught here depends on what is gone before; and therefore they ought to be read together. Many lay hold on these words and mutilate them without understanding the design of the Prophet. This is very absurd: for we ought first to see what the prophets had in view, and by what necessity or cause they were led to speak, what was their condition, and then the general doctrine that may be gafilered from their words. If we wist to read the prophets with benefit, we must first consider the reason why a thing is spoken, and then elicit a general doctrine. Thus we shall be able rightly to apply this passage to a common use, if we first understand why the Prophet said, that the heart of man was insidious. He wished, no doubt, to be more earnest with the Jews; for he saw that they had so much wantonness and obstinacy, that a simple and plain doctrine would not have penetrated into their hearts. The declaration, that they are accursed who trust in men, and that no blessedness can be expected except we rely on God, ought to have been sufficient to move them; but when he saw that there was no sufficient power in such a declaration, he added, “I see how it is, the heart is wicked and vicious; so ye think that you have so much craftiness, that ye can with impunity deride God and his ministers: I, says Jehovah, I will inquire and search; for it belongs to me to examine the hearts of men.”

We hence see that there is an implied reproof, when he says, that the heart is insidious and wicked; ⁽¹⁷⁵⁾ as though he had said, “Ye think yourselves in this instance wise; is not God also wise?” Isaiah says ironically the same,

“Woe to them who go down to Egypt and make secret covenants, and who trust in horses, as though they could deceive me: ye are wise, I also have a portion of wisdom.” (Isaiah 31:1)

Notice especially the expression, “Ye are wise, etc.;” that is, “Ye are not alone wise; leave to me some portions of wisdom, so that I may be wise like yourselves.” So also in this place, “Ye are deceitful and insidious, and think that I can be deceived:” for astute men are ever pleased with their own counsels, and seek to deceive God with mere trumperies. “Ye are,” he says, “very cunning; but I, Jehovah, will search both your hearts and your reins.” I cannot finish the whole to-day.

(175) The early versions and the Targum are neither consistent nor satisfactory as to the beginning of this verse: “Deep is the heart above all things, and it is man,” Septuagint; “Depraved is the heart of all, and inscrutable,” Fulgate; “Hard in heart is man above all things,” Syriac; “The heart, deeper than anything, is human,” Arabic; “Deceitful is the heart above all things, and it is strong.” Targum. Correct, no doubt, is the first clause in the Targum, but not the last. Critics agree as to the first word, “deceitful,” but not as to the word rendered in our version “desperately wicked.” It occurs in all nine times, and four times in other parts of Jeremiah, (Jeremiah 15:18; Jeremiah 17:16; Jeremiah 30:12) and it is rendered “incurable,” except in Jeremiah 17:16. It means to be so bad as to be past endurance or past remedy. Blayney renders it here, “past all hope;” and Horsely, “incurable,” which is perhaps the best word, —

Deceitful the heart above every thing, And incurable it is,
who can know it?

The meaning is, that it is incurably deceitful; hence the question,” Who can know it?” — Ed.

Smith's Bible Commentary

Chapter 17 The sin of Judah is written with a pen of iron, and with the point of a diamond ( Jeremiah 17:1 ):

Interesting that they were using diamonds for pens in those days, isn't it? Diamonds set in iron.

it is graven upon the table of their heart, and upon the horns of your altars; Whilst their children remember their altars and their groves by the green trees upon the high hills. O my mountain in the field, I will give thy substance and all thy treasures to the spoil, and thy high places for sin, throughout all thy borders. And thou, even thyself, shalt discontinue from thine heritage that I gave thee; and I will cause thee to serve thine enemies in the land which thou knowest not: for ye have kindled a fire in mine anger, which shall burn for ever. Thus saith the LORD; Cursed be the man that trusts in man, and makes flesh his arm, and whose heart departs from the LORD ( Jeremiah 17:1-5 ).

And so God pronounces the curse upon those that would trust in an alliance in Egypt to deliver them from this Babylonian invasion. "Cursed be the man who puts his trust in man, and makes the flesh his arm, who has departed from the Lord." That is, from trusting in the Lord.

For he shall be like the heath in the desert, and shall not see when good comes; but shall inhabit the parched places in the wilderness, in a salt land and not inhabited ( Jeremiah 17:6 ).

In contrast to the, "Cursed be the man."

Blessed is the man that trusteth in the LORD, and whose hope the LORD is ( Jeremiah 17:7 ).

Or is the Lord.

For he shall be as a tree planted by the waters, and that spreads out her roots by the river, and shall not see when heat comes, but her leaf shall be green; and shall not worry in the year of drought, neither shall cease from yielding fruit ( Jeremiah 17:8 ).

So the cursing upon those that would trust in man, in the arm of flesh and not the Lord, but the blessing upon those that would trust in the Lord. Those who trust in man and the arm of flesh will be dried, withered, dead, uninhabited. Those that trust in the Lord will be like a tree planted by the waters that doesn't even know when summer comes because of the freshness that it draws out from that water.

Now verse Jeremiah 17:9 :

The heart is deceitful above all things, and desperately wicked: who can know it? ( Jeremiah 17:9 )

God's talking about your heart and my heart. Socrates cried, "Man, know thyself." But who really does know himself? The scripture says, "Thou, O Lord, searches the heart and the reins." God knows my heart better than I know it. God knows what deception is there. And it is easy for us to become deceived. It's easy for us to follow a vain philosophy. It's easy for us to take that adage, "The end justifies the means." And so our means become perverse, crooked.

Paul the apostle talks about those who say, "Well, our lies bring glory to God so God shouldn't judge us for lying." Or those who would say, "Well, if I sin I'm only proving that God is telling the truth when He said all have sinned. So how can God judge me for proving Him to be speaking the truth? I'm only helping prove the truth of God's Word so God really can't judge me because I'm only proving what He said is true." And Paul speaks out against the perversity of such kind of logic and how God will judge all.

Now there are those who in the name of the Lord are doing crooked and perverse things. And if you talk to them about it, challenge them, they would be shocked. They would be disturbed. "My, brother! You know, you're judging me." The Bible says judge righteous judgment. I think that we've been put off a long time because we are afraid of people saying, "Well, you're judging, you know." The Bible says, "By their fruits ye shall know them" ( Matthew 7:16 ). And it is wrong to use deceit and lies and gimmicks to try to extract funds from the people of God in order to support your program. I don't care how righteous or good your program may be.

My wife told me not to get into this tonight. It's right here in the scripture. It just came along. I just... I cannot understand men advertising their fasting and prayer when Jesus said, "When you fast, anoint your face. Wash yourself that you might look cheerful and all. That you don't appear unto men to fast. And your Father which sees in secret, He'll reward you. And when you pray, don't go out on the street corner, but go into your closet and shut the door." And when some guy sends letters out all over the country saying, "I'm going to spend some time fasting and praying, send me your requests with your fifty dollar check because I want to pray for you, too," something's wrong. Desperately wrong.

"The heart is deceitful, and desperately wicked. Who can know it?" But God declares, "I the Lord search the heart. I try the reins." That is, the motivations. "Even to give every man according to his ways." Now Jesus tells us that we are to be careful that we don't do our righteousness before men to be seen of men because we have our reward. Now Jesus plainly warns us about that. There is a way that I can do my righteousness so that people see me and they say, "Oh my, isn't he spiritual?" And we've got to watch out for this, because it is such a deceiving, terrible thing. My old pride and my old flesh wants people to think that I am a spiritual man of God. I like people when I walk by to whisper, "Oh, isn't he spiritual? Oh." My flesh just really enjoys that. And so it's easy for me to get little spiritual affectations that my mind isn't really necessarily upon God. As I stand there, you lift your head upward and close your eyes because that looks more spiritual. I wonder if people are seeing me now. Surely they'll know I'm very spiritual. I hope they're watching. And then if you go up on your tiptoes it even looks a little more, you know, spiritual. But my mind, what am I thinking? Am I thinking, "I hope they're watching. I hope they see. I hope they notice. I hope they realize how spiritual I am." God said, "Look, I'm searching the heart. I'm trying the motives."

Now the Bible tells us that one day all of our works are going to be judged by fire. And much of what we have done is going to go poof! It's going to go up in smoke. "Wait a minute, Lord, did I not prophesy in Thy name? Didn't I work miracles in Your name? Didn't I heal the sick in Your name? Lord!"

I the Lord search the heart, I try the reins ( Jeremiah 17:10 ),

All of your works are wood, hay and stubble. They were done to be seen of men. They were done for your own glory and to spread abroad your own name. You named your chapels and your universities and all after your own name. Sad. Sad. What a day of awakening it's going to be.

"The heart is deceitful above all things and desperately wicked." Now David realizing this, realizing that he didn't even know his own heart because of the deceitfulness of the heart, said, "Thou O Lord hast searched me and You know me. You know my thoughts in their origin. Such knowledge," he said, "is too great for me. I cannot attain it" ( Psalms 139:1 , Psalms 139:6 ). I cannot really attain the true knowledge of myself. But then he said, "Search me, O God, and know my heart: try me, and know my thoughts. And see if there be some way of wickedness in me, and lead me in Your way eternal" ( Psalms 139:23-24 ).

Now the man who understands and knows that his heart is deceitful and desperately wicked is the man who will join David's prayer and say, "O God, You search my heart. You know. You try me. And God, if there's something there that is wrong, is displeasing to You, reveal it to me, Lord." I don't want to be deceived. I don't want to be deceiving myself. I don't want to stand before God and suddenly find all that I've done wiped out in a puff of smoke as the fire consumes all of that work of wood, hay and stubble. Jesus said, "You've not chosen Me, but I've chosen you, and ordained you, that you should be My disciples, that you should bring forth fruit and that your fruit should remain" ( John 15:16 ). That's what I want, remaining fruit. So God help us. He's searching our hearts. He tries the rein. And He's going

to give to every man according to his ways ( Jeremiah 17:10 )

What's in my heart? Why did I do it? That's what's going to be judged. God is going to give to him

according to the fruit of his doings. As the partridge sits on eggs, and doesn't hatch them; so is he that gets riches, and not by right ( Jeremiah 17:10-11 ),

But by wrong means. He is accumulating wealth.

he shall leave them in the midst of his days, and at his end he shall be a fool. A glorious high throne from the beginning is the place of our sanctuary ( Jeremiah 17:11-12 ).

That place of our sanctuary is God's glorious high throne.

O LORD, the hope of Israel, all that forsake thee shall be ashamed, and they that depart from me shall be written in the earth, because they have forsaken the LORD, the fountain of living waters ( Jeremiah 17:13 ).

Takes us back to the first cry of God against Israel in that they have committed two evils: "They have forsaken Me the fountain of living waters, and hewed out for themselves cisterns that can hold no water" ( Jeremiah 2:13 ).

Heal me, O LORD, and I shall be healed; save me, and I shall be saved: for thou art my praise. Behold, they say unto me, Where is the word of the LORD? let it come now. As for me, I have not hastened from being a pastor to follow thee: neither have I desired the woeful day; thou knowest: that which came out of my lips was right before thee ( Jeremiah 17:14-16 ).

He's not rejoicing in the things that he is saying.

Be not a terror unto me: thou art my hope in the day of evil. Let them be confounded that persecute me, but let not me be confounded: let them be dismayed, but let not me be dismayed: bring upon them the day of evil, and destroy them with double destruction ( Jeremiah 17:17-18 ).

Now the Lord spoke to him concerning the gates where the king went in and went out, and He said, "Now go down to the gate and when the king comes in give him this message."

Thus said the LORD unto me; Go and stand in the gate of the children of the people, whereby the kings of Judah come in, and by the which they go out, and in all the gates of Jerusalem; And say unto them, Hear ye the word of the LORD, ye kings of Judah, and all Judah, and all the inhabitants of Jerusalem, that enter in by these gates: Thus saith the LORD; Take heed to yourselves, and bear no burden on the sabbath day, nor bring it in by the gates of Jerusalem; Neither carry forth a burden out of your houses on the sabbath day, neither do ye any work, but hallow ye the sabbath day, as I have commanded your fathers. But they obeyed not, neither inclined their ear ( Jeremiah 17:19-23 ),

Now that is, their fathers obeyed not. "I told your fathers not to do this," God is saying, "but they didn't obey Me. Neither did they incline their ear."

but made their neck stiff, that they might not hear, nor receive instruction. And it shall come to pass, if ye diligently hearken unto me, saith the LORD, to bring in no burden through the gates of this city on the sabbath day, but hallow the sabbath day, to do no work therein; Then shall there enter into the gates of this city kings and princes sitting upon the throne of David, riding in chariots and on horses, they, and their princes, the men of Judah, and the inhabitants of Jerusalem: and this city shall remain for ever ( Jeremiah 17:23-25 ).

God is still holding out the opportunity of salvation and hope to them. Even at this late stage of their backsliding. Even when the judgment is hanging over their head. Even when Babylon is marching to destroy this place. God is still holding out to them a hope. "Just turn to Me, just obey Me, and the gates here, the kings and the princes will be passing through forever. You'll never be destroyed or put out of the land." God's mercies just are so extensive. They're right up until the moment a person dies. God extends His mercy. Oh, how merciful is our God!

And they shall come from the cities of Judah, and from the places about Jerusalem, and from the land of Benjamin, and from the plain, and from the mountains, and from the south, bringing burnt offerings, and sacrifices, and meat offerings, and incense, and bringing sacrifices of praise, unto the house of the LORD ( Jeremiah 17:26 ).

It can happen. It can happen to you. Just turn back to Me. Just obey My commandments.

But if you will not hearken unto me to hallow the sabbath day, and not to bear a burden, even entering in at the gates of Jerusalem on the sabbath day; then will I kindle a fire in the gates thereof, and it shall devour the palaces of Jerusalem, and it shall not be quenched ( Jeremiah 17:27 ). "

Dr. Constable's Expository Notes

Judah’s indelible sin and sin’s deceitfulness 17:1-18

The next five sections (Jeremiah 17:1-18) continue the theme of Judah’s guilt from the previous chapter. These pericopes have obvious connections with one another, but they were evidently originally separate prophecies. Jeremiah 17:1-4 are particularly ironic.

Dr. Constable's Expository Notes

The Old Testament frequently uses "heart" (Heb. leb) to identify the source of a person’s thinking and acting. It describes the root of unconscious as well as conscious motivation.

The human heart is deceptive; we may think we know why we do something, but really we may be doing it for another reason. It is naturally incurably sick, really totally depraved, and in need of healing. No one really understands his or her own corrupt heart, nor do we understand why our hearts behave as they do.

"Unregenerate human nature is in a desperate condition without divine grace . . ." [Note: Harrison, Jeremiah and . . ., p. 106.]

Gill's Exposition of the Whole Bible

The heart is deceitful above all things,.... This is the source of the idolatry and creature confidence of the Jews, sins which were the cause of their ruin; and though what is here said is particularly applicable to their hearts, yet is in general true of the heart of every man; which is "deceitful", and deceiving; and puts a cheat upon the man himself whose it is: it deceives him with respect to sin; it proposes it to him under the notion of pleasure; it promises him a great deal in it, but does not yield a real pleasure to him; it is all fancy and imagination; a mere illusion and a dream; and what it gives is very short lived; it is but for a season, and ends in bitterness and death: or it proposes it under the notion of profit; it promises him riches, by such and such sinful ways it suggests; but, when he has got them, he is the loser by them; these deceitful riches choke the word, cause him to err from the faith, pierce him through with many sorrows, and endanger the loss of his soul: it promises honour and preferment in the world, but promotes him to shame; it promises him liberty, but brings him into bondage; it promises him impunity, peace, and security, when sudden destruction comes: it deceives him in point of knowledge; it persuades him that he is a very knowing person, when he is blind and ignorant, and knows nothing as he ought to know; and only deceives himself; for there is no true knowledge but of God in Christ, and of a crucified Christ, and salvation by him; see 1 Corinthians 3:18 it deceives in the business of religion; it makes a man believe that he is a very holy and righteous man, and in a fair way for heaven, when he is far from that, and the character it gives him; in order to this, it suggests to him that concupiscence or lust, or the inward workings of the mind, are not sin; and it is only on this principle that it can be accounted for, that Saul, before conversion, or any other man, should be led into such a mistake, as to conclude that, touching the righteousness of the law, he was blameless: it represents other sins as mere peccadillos, as little sins, and not to be regarded; and even puts the name of virtue on vices; profuseness and prodigality it calls liberality, and doing public good; and covetousness has the name of frugality and good economy: it directs men to compare themselves and their outward conduct with others, that are very profane and dissolute; and from thence to form a good character of themselves, as better than others; and as it buoys up with the purity of human nature, so with the power of man's freewill to do that which is good, and particularly to repent at pleasure; and it puts the profane sinner upon trusting to the absolute mercy of God, and hides from him his justice and holiness; and it puts others upon depending upon the outward acts of religion, or upon speculative notions, to the neglect of real godliness; see James 1:22. The man of a deceitful heart, the hypocrite, tries to deceive God himself, but he cannot; he oftentimes deceives men, and always himself; so do the profane sinner, the self-righteous man, and the false teacher; who attempts to deceive the very elect, but cannot; yea, a good man may be deceived by his own heart, of which Peter is a sad instance, Matthew 26:33. The heart is deceitful to a very great degree, it is superlatively so; "above all", above all creatures; the serpent and the fox are noted for their subtlety, and wicked men are compared to them for it; but these comparisons fall short of expressing the wicked subtlety and deceit in men's hearts; yea, it is more deceitful to a man than the devil, the great deceiver himself; because it is nearer to a man, and can come at him, and work upon him, when Satan cannot: or "about", or "concerning all things" q; it is so in everything in which it is concerned, natural, civil, or religious, and especially the latter. The Septuagint version renders it "deep"; it is an abyss, a bottomless one; there is no fathoming of it; the depths of sin are in it; see Psalms 64:6 and, seeing it is so deceitful, it should not be trusted in; a man should neither trust in his own heart, nor in another's, Proverbs 28:26, "and desperately wicked": everything in it is wicked; the thoughts of it are evil; the imaginations of the thoughts are so; even every imagination, and that only, and always, Genesis 6:5 the affections are inordinate; the mind and conscience are defiled; the understanding darkened, so dark as to call evil good, and good evil; and the will obstinate and perverse: all manner of sin and wickedness is in it; it is the cage of every unclean bird, and the hold of every foul spirit; all sin is forged and framed in it; and all manner of evil comes out of it, Revelation 18:1 yea, it is wickedness itself, Psalms 5:9, it is so even to desperation; it is "incurably wicked" r, as it may be rendered; it is so without the grace of God, and blood of Christ:

who can know it? angels do not, Satan cannot; only the spirit of a man can know the things of a man within him; though the natural man does not know the plague of his own heart; the Pharisee and perfectionist do not, or they would not say they were without sin; such rant arises from the ignorance of their own hearts; only a spiritual man knows his own heart, the plague of it, the deceitfulness and wickedness in it; and he does not know it all; God only knows it fully, as is expressed in the next words, which are an answer to the question; see 1 Corinthians 2:11.

Henry's Complete Commentary on the Bible

      5 Thus saith the LORD; Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD.   6 For he shall be like the heath in the desert, and shall not see when good cometh; but shall inhabit the parched places in the wilderness, in a salt land and not inhabited.   7 Blessed is the man that trusteth in the LORD, and whose hope the LORD is.   8 For he shall be as a tree planted by the waters, and that spreadeth out her roots by the river, and shall not see when heat cometh, but her leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit.   9 The heart is deceitful above all things, and desperately wicked: who can know it?   10 I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings.   11 As the partridge sitteth on eggs, and hatcheth them not; so he that getteth riches, and not by right, shall leave them in the midst of his days, and at his end shall be a fool.

      It is excellent doctrine that is preached in these verses, and of general concern and use to us all, and it does not appear to have any particular reference to the present state of Judah and Jerusalem. The prophet's sermons were not all prophetical, but some of them practical; yet this discourse, which probably we have here only the heads of, would be of singular use to them by way of caution not to misplace their confidence in the day of their distress. Let us all learn what we are taught here,

      I. Concerning the disappointment and vexation those will certainly meet with who depend upon creatures for success and relief when they are in trouble (Jeremiah 17:5; Jeremiah 17:6): Cursed be the man that trusts in man. God pronounces him cursed for the affront he thereby puts upon him. Or, Cursed (that is, miserable) is the man that does so, for he leans upon a broken reed, which will not only fail him, but will run into his hand and pierce it. Observe, 1. The sin here condemned; it is trusting in man, putting that confidence in the wisdom and power, the kindness and faithfulness, of men, which should be placed in those attributes of God only, making our applications to men and raising our expectations from them as principal agents, whereas they are but instruments in the hand of Providence. It is making flesh the arm we stay upon, the arm we work with and with which we hope to work our point, the arm under which we shelter ourselves and on which we depend for protection. God is his people's arm,Isaiah 32:2. We must not think to make any creature to be that to us which God has undertaken to be. Man is called flesh, to show the folly of those that make him their confidence; he is flesh, weak and feeble as flesh without bones or sinews, that has no strength at all in it; he is inactive as flesh without spirit, which is a dead thing; he is mortal and dying as flesh, which soon putrefies and corrupts, and is continually wasting. Nay, he is false and sinful, and has lost his integrity; so his being flesh signifies, Genesis 6:3. The great malignity there is in this sin; it is the departure of the evil heart of unbelief from the living God. Those that trust in man perhaps draw nigh to God with their mouth and honour him with their lips, they call him their hope and say that they trust in him, but really their heart departs from him; they distrust him, despise him, and decline a correspondence with him. Cleaving to the cistern is leaving the fountain, and is resented accordingly. 3. The fatal consequences of this sin. He that puts a confidence in man puts a cheat upon himself; for (Jeremiah 17:6; Jeremiah 17:6) he shall be like the heath in the desert, a sorry shrub, the product of barren ground, sapless, useless, and worthless; his comforts shall all fail him and his hopes be blasted; he shall wither, be dejected in himself and trampled on by all about him. When good comes he shall not see it, he shall not share in it; when the times mend they shall not mend with him, but he shall inhabit the parched places in the wilderness; his expectation shall be continually frustrated; when others have a harvest he shall have none. Those that trust to their own righteousness and strength, and think they can do well enough without the merit and grace of Christ, thus make flesh their arm, and their souls cannot prosper in graces or comforts; they can neither produce the fruits of acceptable services to God nor reap the fruits of saving blessings from him; they dwell in a dry land.

      II. Concerning the abundant satisfaction which those have, and will have, who make God their confidence, who live by faith in his providence and promise, who refer themselves to him and his guidance at all times and repose themselves in him and his love in the most unquiet times, Jeremiah 17:7; Jeremiah 17:8. Observe, 1. The duty required of us--to trust in the Lord, to do our duty to him and then depend upon him to bear us out in doing it--when creatures and second causes either deceive or threaten us, either are false to us or fierce against us, to commit ourselves to God as all-sufficient both to fill up the place of those who fail us and to protect us from those who set upon us. It is to make the Lord our hope, his favour the good we hope for and his power the strength we hope in. 2. The comfort that attends the doing of this duty. He that does so shall be as a tree planted by the waters, a choice tree, about which great care has been taken to set it in the best soil, so far from being like the heath in the wilderness; he shall be like a tree that spreads out its roots, and thereby is firmly fixed, spreads them out by the rivers, whence it draws abundance of sap, which denotes both the establishment and the comfort which those have who make God their hope; they are easy, they are pleasant, and enjoy a continual security and serenity of mind. A tree thus planted, thus watered, shall not see when heat comes, shall not sustain any damage from the most scorching heats of summer; it is so well moistened from its roots that it shall be sufficiently guarded against drought. Those that make God their hope, (1.) They shall flourish in credit and comfort, like a tree that is always green, whose leaf does not wither; they shall be cheerful to themselves and beautiful in the eyes of others. Those who thus give honour to God by giving him credit God will put honour upon, and make them the ornament and delight of the places where they live, as green trees are. (2.) They shall be fixed in an inward peace and satisfaction: They shall not be careful in a year of drought, when there is want of rain; for, as the tree has seed in itself, so it has its moisture. Those who make God their hope have enough in him to make up the want of all creature-comforts. We need not be solicitous about the breaking of a cistern as long as we have the fountain. (3.) They shall be fruitful in holiness, and in all good works. Those who trust in God, and by faith derive strength and grace from him, shall not cease from yielding fruit; they shall still be enabled to do that which will redound to the glory of God, the benefit of others, and their own account.

      III. Concerning the sinfulness of man's heart, and the divine inspection it is always under, Jeremiah 17:9; Jeremiah 17:10. It is folly to trust in man, for he is not only frail, but false and deceitful. We are apt to think that we trust in God, and are entitled to the blessings here promised to those who do so. But this is a thing about which our own hearts deceive us as much as any thing. We think that we trust in God when really we do not, as appears by this, that our hopes and fears rise or fall according as second causes smile or frown.

      1. It is true in general. (1.) There is that wickedness in our hearts which we ourselves are not aware of and do not suspect to be there; nay, it is a common mistake among the children of men to think themselves, their own hearts at least, a great deal better than they really are. The heart, the conscience of man, in his corrupt and fallen state, is deceitful above all things. It is subtle and false; it is apt to supplant (so the word properly signifies); it is that from which Jacob had his name, a supplanter. It calls evil good and good evil, puts false colours upon things, and cries peace to those to whom peace does not belong. When men say in their hearts (that is, suffer their hearts to whisper to them) that there is no God, or he does not see, or he will not require, or they shall have peace though they go on; in these, and a thousand similar suggestions the heart is deceitful. It cheats men into their own ruin; and this will be the aggravation of it, that they are self-deceivers, self-destroyers. Herein the heart is desperately wicked; it is deadly, it is desperate. The case is bad indeed, and in a manner deplorable and past relief, if the conscience which should rectify the errors of the other faculties is itself a mother of falsehood and a ring-leader in the delusion. What will become of a man if that in him which should be the candle of the Lord give a false light, if God's deputy in the soul, that is entrusted to support his interests, betrays them? Such is the deceitfulness of the heart that we may truly say, Who can know it? Who can describe how bad the heart is? We cannot know our own hearts, not what they will do in an hour of temptation (Hezekiah did not, Peter did not), not what corrupt dispositions there are in them, nor in how many things they have turned aside; who can understand his errors? Much less can we know the hearts of others, or have any dependence upon them. But, (2.) Whatever wickedness there is in the heart God sees it, and knows it, is perfectly acquainted with it and apprised of it: I the Lord search the heart. This is true of all that is in the heart, all the thoughts of it, the quickest, and those that are most carelessly overlooked by ourselves--all the intents of it, the closest, and those that are most artfully disguised, and industriously concealed from others. Men may be imposed upon, but God cannot. He not only searches the heart with a piercing eye, but he tries the reins, to pass a judgment upon what he discovers, to give every thing its true character and due weight. He tries it, as the gold is tried whether it be standard or no, as the prisoner is tried whether he be guilty or no. And this judgment which he makes of the heart is in order to his passing judgment upon the man; it is to give to every man according to his ways (according to the desert and the tendency of them, life to those that walked in the ways of life, and death to those that persisted in the paths of the destroyer) and according to the fruit of his doings, the effect and influence his doings have had upon others, or according to what is settled by the word of God to be the fruit of men's doings, blessings to the obedient and curses to the disobedient. Note, Therefore God is Judge himself, and he alone, because he, and none besides, knows the hearts of the children of men.

      2. It is true especially of all the deceitfulness and wickedness of the heart, all its corrupt devices, desires, and designs. God observes and discerns them; and (which is more than any man can do) he judges of the overt act by the heart. Note, God knows more evil of us than we do of ourselves, which is a good reason why we should not flatter ourselves, but always stand in awe of the judgment of God.

      IV. Concerning the curse that attends wealth unjustly gotten. Fraud and violence had been reigning crying sins in Judah and Jerusalem; now the prophet would have those who had been guilty of these sins, and were now stripped of all they had, to read their sin in their punishment (Jeremiah 17:11; Jeremiah 17:11): He that gets riches and not by right, though he may make them his hope, shall never have joy of them. Observe, It is possible that those who use unlawful means to get wealth may succeed therein and prosper for a time; and it is a temptation to many to defraud and oppress their neighbours when there is money to be got by it. He who has got treasures by vanity and a lying tongue may hug himself in his success, and say, I am rich; nay, and I am innocent too (Hosea 12:8), but he shall leave them in the midst of his days; they shall be taken from him, or he from them; God shall cut him off with some surprising stroke then when he says, Soul, take thy ease, thou hast goods laid up for many years,Luke 12:19; Luke 12:20. He shall leave them to he knows not whom, and shall not be able to take any of his riches away with him. It intimates what a great vexation it is to a worldly man at death that he must leave his riches behind him; and justly may it be a terror to those who got them unjustly, for, though the wealth will not follow them to another world, the guilt will, and the torment of an everlasting, Son, remember,Luke 16:25. Thus, at his end, he shall be a fool, a Nabal, whose wealth did him no good, which he had so sordidly hoarded, when his heart became dead as a stone. He was a fool all along; sometimes perhaps his own conscience told him so, but at his end he will appear to be so. Those are fools indeed who are fools in their latter end; and such multitudes will prove who were applauded as wise men, that did well for themselves,Psalms 49:13; Psalms 49:18. Those that get grace will be wise in the latter end, will have the comfort of it in death and the benefit of it to eternity (Proverbs 19:20); but those that place their happiness in the wealth of the world, and, right or wrong, will be rich, will rue the folly of it when it is too late to rectify the fatal mistake. This is like the partridge that sits on eggs and hatches them not, but they are broken (as Job 39:15), or stolen (as Isaiah 10:14), or they become addle: some sort of fowl there was, well known among the Jews, whose case this commonly was. The rich man takes a great deal of pains to get an estate together, and sits brooding upon it, but never has any comfort nor satisfaction in it; his projects to enrich himself by sinful courses miscarry and come to nothing. Let us therefore be wise in time--what we get to get it honestly, and what we have to use it charitably, that we may lay up in store a good foundation and be wise for eternity.
