Psalms 90:12

Clarke's Commentary

Verse Psalms 90:12. So teach us to number our days — Let us deeply consider our own frailty, and the shortness and uncertainty of life, that we may live for eternity, acquaint ourselves with thee, and be at peace; that we may die in thy favour and live and reign with thee eternally.

Bridgeway Bible Commentary

Psalms 90:0 Making the most of a short life

God alone is permanent and enduring, and therefore the only true security is found in him (1-2). Human life, by contrast, is short and uncertain, and is brought to an end as God decides and when he chooses. No matter how long a person lives, even to a thousand years, the number of years is insignificant compared with the timelessness of God (3-6).
Sin has spoiled human life and brought God’s judgment upon people in the form of life’s troubles and finally death (7-10). The ungodly live to please themselves. They do not fear God and do not consider that they are spending their lives building up God’s judgment against them. Those who love God should therefore seek God’s wisdom, so that they might use their short lives in the best way possible (11-12). Since the psalmist wants to live his life wisely, he asks for God’s help. Then sorrow will be replaced by joy, and his life will become one of fruitful service for God (13-17).

Coffman's Commentaries on the Bible

MOSES' PRAYER

"So teach us to number our days, That we may get us a heart of wisdom. Hearken, O Jehovah; how long? And let it repent thee concerning thy servants. O satisfy us in the morning with thy lovingkindness, That we may rejoice and be glad all our days. Make us glad according to the days wherein thou hast afflicted us, And the years wherein we have seen evil. Let thy work appear unto thy servants, And thy glory upon their children. And let the favor of the Lord our God be upon us; And establish thou the work of our hands upon us; Yea, the work of our hands establish thou it."

"Teach us to number our days… that we may get… a heart of wisdom" This is a prayer that God will teach men to live as dying men should live, always taking account of the brevity and uncertainty of life and of the inevitable accounting before God in the Final Day. What a contrast is this with the attitude of many wicked people who live exactly as if they expected to live forever!

"Return… repent thee" This is a plea, "For a restoration of God's favor."International Critical Commentary, Vol. II, p. 276. To be sure, God does not "repent" in the human sense, but when the repentance and prayers of his people permit it, God indeed will restore them to favor.

"Make us glad according to the days wherein thou hast afflicted us" The two clauses in this and in the second half of the verse are synonymous pleadings with God to, "Balance the evil with good things."C. M. Miller, co-author with Anthony L. Ash, p. 317. It is as if Moses is saying, "O God, let us at least have good times that are as long as the evil times we have suffered."

"The prevailing thought in this section is one of confidence in the Lord's kindness and power. The psalmist knows that it is only God's favor that renews the sense of gladness and truly prospers the works of men."The Interpreter's Bible, Vol. IV, p. 492.

"Let thy work appear unto thy servants, and thy glory upon their children" Barnes understood this to mean, "Let us see thy power displayed in removing the calamities and in restoring our days of prosperity."Barnes' Notes on the Old Testament (Grand Rapids: Baker Book House, a 1987 reprint of the 1878 edition), op. cit., p. 10. It was especially a concern of Moses that the next generation of Israel (their children) would also be made aware of God's glory.

"Let the favor of God be upon us… establish the work of our hands" Those who do God's will during their earthly pilgrimage are happy indeed. "Blessed are the dead who die in the Lord, assuredly, for they shall rest from their labors, and their work's follow with them" (Revelation 14:13). This indicates that the works of righteous people shall indeed survive them and follow them even to the Judgment of the Great Day. This must surely be what the psalmist meant by "establish the work of our hands." How glorious is the apostolic assurance that, "We know that our labor is not in vain in the Lord" (1 Corinthians 15:58).

Alexander Maclaren has a marvelous paragraph on this with which we wish to conclude this chapter.

Fleeting as our days are, they are ennobled by our being permitted to be God's "tools"; and although we the workers have to pass, our work may be established. That life will not die which has done the will of God. But we must walk in the favor of God, so that there can flow down from us deeds which breed not shame but shall outlast the perishable earth and follow their doers into the dwelling places of those eternal habitations.Alexander Maclaren, Vol. III, p. 13.

Barnes' Notes on the Whole Bible

So teach us to number our days - literally, “To number our days make us know, and we will bring a heart of wisdom.” The prayer is, that God would instruct us to estimate our days aright: their number; the rapidity with which they pass away; the liability to be cut down; the certainty that they must soon come to an end; their bearing on the future state of being.

That we may apply our hearts unto wisdom - Margin, “Cause to come.” We will bring, or cause to come, a heart of wisdom. By taking a just account of life, that we may bring to it a heart truly wise, or act wisely in view of these facts. The prayer is, that God would enable us to form such an estimate of life, that we shall be truly wise; that we may be able to act “as if” we saw the whole of life, or as we should do if we saw its end. God sees the end - the time, the manner, the circumstances in which life will close; and although he has wisely hidden that from us, yet he can enable us to act as if we saw it for ourselves; to have the same objects before us, and to make as much of life, “as if” we saw when and how it would close. If anyone knew when, and where, and how he was to die, it might be presumed that this would exert an important influence on him in forming his plans, and on his general manner of life. The prayer is, that God would enable us to act “as if” we had such a view.

Calvin's Commentary on the Bible

12.Teach us so to number our days. Some translate to the number of our days, which gives the same sense. As Moses perceived that what he had hitherto taught is not comprehended by the understandings of men until God shine upon them by his Spirit, he now sets himself to prayer. It indeed seems at first sight absurd to pray that we may know the number of our years. What? since even the strongest scarcely reach the age of fourscore years, is there any difficulty in reckoning up so small a sum? Children learn numbers as soon as they begin to prattle; and we do not need a teacher in arithmetic to enable us to count the length of a hundred upon our fingers. So much the fouler and more shameful is our stupidity in never comprehending the short term of our life. Even he who is most skillful in arithmetic, and who can precisely and accurately understand and investigate millions of millions, is nevertheless unable to count fourscore years in his own life. It is surely a monstrous thing that men can measure all distances without themselves, that they know how many feet the moon is distant from the center of the earth, what space there is between the different planets; and, in short, that they can measure all the dimensions both of heaven and earth; while yet they cannot number threescore and ten years in their own case. It is therefore evident that Moses had good reason to beseech God for ability to perform what requires a wisdom which is very rare among mankind. The last clause of the verse is also worthy of special notice. By it he teaches us that we then truly apply our hearts to wisdom when we comprehend the shortness of human life. What can be a greater proof of madness than to ramble about without proposing to one’s self any end? True believers alone, who know the difference between this transitory state and a blessed eternity, for which they were created, know what ought to be the aim of their life. No man then can regulate his life with a settled mind, but he who, knowing the end of it, that is to say death itself, is led to consider the great purpose of man’s existence in this world, that he may aspire after the prize of the heavenly calling.

Smith's Bible Commentary

Psalms 90:1-17 is a psalm of Moses. Now Moses was also a writer and he wrote psalms and songs, and this is one of the psalms of Moses.

LORD [or Jehovah], thou hast been our dwelling place in all generations. Before the mountains were brought forth, or ever you had formed the earth and the world, even from everlasting to everlasting, thou art God ( Psalms 90:1-2 ).

Declaring the eternal nature of God. Before the world ever existed, from everlasting to everlasting.

The word everlasting is an interesting Hebrew word. It is a word that literally means the vanishing point. To understand it, think back as far as you can think back. Now the sun, they say, is losing about... been a while since I've read how much it's losing... something like 200 million tons per second of mass. At that rate, in ten billion years it will no longer be able to support life upon the earth. So if you want something to worry about, think about that.

So because the sun is losing this much mass, the sun could not have always existed. Because if you added that much mass to the sun back to infinity, it would have meant that the sun at one time filled the entire universe. If you kept adding it would. So the sun is gradually reducing. It's like Herschel Genes, the scientist said that the earth is like a giant clock that was wound up and is slowly winding down. The first and second laws of thermodynamics, laws of entropy, and the gradual erosion and wearing down of the material world.

So you have to think of a time when the earth didn't exist if you go back far enough. So in your mind go back just as far as you can possibly think back. Now as you go back in your mind, as far as you can go back, there comes a point, it's sort of a vanishing point. In other words, you just can't think of anything before that. It sort of fades out into a vanishing point. That's this Hebrew word everlasting, from this vanishing point.

Now in your mind think forward as far as you can think on into eternity. Now they say that if a little bird will go down here to Huntington Beach and take a drop of water in its beak out of the surf there, and every morning as the sun would rise, would take one hop towards New York. And when the little bird arrived in New York, it would drop that water in New York harbor. And then start back a hop a day towards Huntington Beach again. By the time that little bird emptied the Pacific Ocean into the Atlantic Ocean, the first day of eternity would just be getting its start. So think of out in the future to the vanishing point, you know. You think out so far and then it just vanishes. So the Hebrew word has that as its meaning. Actually, literally from the vanishing point as far as I can think until my mind just hits the vanishing point, to as far out as I can think this way, till my mind hits the vanishing point, you're God. You've existed. You will exist.

There is even a Hebrew word that is stronger than that. It is beyond the vanishing point. You know, when I get to the vanishing point, and then out beyond that. And that's the strongest word in Hebrew for the eternity. It's beyond the vanishing point. But vanishing point is far enough for me. From everlasting to everlasting God has existed.

You turn man to destruction; and you say, Return, ye children of men. For a thousand years in your sight are but as yesterday when it is past, and as a watch in the night ( Psalms 90:3-4 ).

So the relativity of time. A thousand years is just like a day as far as the Lord is concerned. Now Peter tells this in talking to us about the coming again of Jesus Christ. He said, "In the last days, there will be scoffers that will come saying, 'Oh, where is the promise of His coming? Since our fathers have fallen asleep, everything continues as they were from the beginning.'" ( 2 Peter 3:3 , 2 Peter 3:4 ) God's not going to come. You know, where is it? Where is the promise? He is not here. And Peter said you've got to realize that a thousand years is as a day unto the Lord and a day is as a thousand years. So time is only relative to us. We think in the terms of time. We always think in terms of linear time. Here's the beginning; here's the end. Here's my birth; here's my death. Time in a linear way.

But that's because we are involved in matter. But if we weren't matter, then time wouldn't matter. Time only matters to matter. According to Einstein's theory of relativity, actually, time doesn't exist. Only except in matter. And so time can be stretched if you're going fast enough. So, in according to his theory, that if you can accelerate yourself to the speed of light, time would stand still. So if you could accelerate yourself to the speed of light and head out for the Andromeda galaxy, about... oh, let's not go to the Adromeda galaxy, that's too far. Let's go to Proxima, or Alpha Centauri. They're our closest solar neighbors. Traveling on this ray of light you could get to Centauri, Alpha Centauri, you could get there in four-and-a-half years. You could make the round-trip in nine years. But when you got back though, you would be the same age. Time would have stood still for you because of the speed at which you were traveling. When you got back, the earth would be nine years older. Your wife would be nine years older than you are at this point. Now, if you went further, if you did go to Andromeda galaxy, one million five hundred thousand light years out there, you'd come back in three million years. Now the whole earth would be different by that time. You'd look around you wouldn't find any of your friends. But you would only be, you know, a matter of hours older, because time would have stood still because of the speed you were traveling. Because if you travel that fast, you're going to turn into energy, and because you have no materials, you're just energy at that point, then time ceases to exist. This is the idea of the relativity, Einstein's theory of relativity. And so there's no way that we can really prove it. So you just have to accept it because he was a smart man.

But it is interesting that the Bible does hint to relativity of time as far as God is concerned. "A thousand years in Your sight is like yesterday when it's past." And, as Peter said, "A day is as a thousand years to the Lord, a thousand years is as a day."

Now that is interesting in the light of in the book of Hosea, he speaks of Israel sort of being out of the land, dispersed for two years. And he said, "And in the third year, I will raise her up and she will dwell in the land." Or, "for two days," rather, "and in the third day... " "After two days He will revive us, and in the third day He will raise us up, and we shall live in His sight" ( Hosea 6:2 ). And so Israel was destroyed and dispersed from the land for about two thousand years. And now they've been raised up again. And so, a thousand years is as a thousand years to the Lord... a day is as a thousand years.

So you say, "Oh, but the Lord's waiting so long to come back." Yeah, a couple days. Relativity of time.

You carry them away as with a flood; they are as a sleep: in the morning they are like grass which grows up. In the morning it flourishes, it grows up; in the evening and it cuts down, and withers ( Psalms 90:5-6 )

So life is just so temporal.

We are consumed by your anger, and by your wrath we are troubled. You have set our iniquities before thee, our secret sins are in the light of your countenance. For all of our days are passed away in thy wrath: we spend our years as a tale that is told ( Psalms 90:7-9 ).

Now, not only is time relative, and this is where we really come into trouble understanding this, because it really begins to get weird at this point. When you are released from this linear timeframe that we are existing in, and you can enter into the timelessness of eternity, there is then no past and or no future, but everything is present, because now you're released from time. And in time, we know past, present, future. But released from the linear time zone, then the past or the future do not exist; everything is now in the present. Now the writer of Eccleciastes tried to describe that and he only made it more confusing. But, of course, our minds can't grasp it anyhow, so it would just boggle our minds to try to conceive it.

But that which is past, he said, is now. And that which shall be has already been. And God requires that which is past. So figure that one out and you've got eternity wired. Everything happening now, so that in this relativity of time, in reality, our lives are spent like a story that's already been told. We're like a re-run as far as God is concerned, because God living outside of the time dimension can see the whole picture at once.

As James said, "You know the end from the beginning." Or James said actually, "Known unto Him are all things from the beginning," because He is outside of the linear timeframe. Thus, as God looks down, He sees the whole picture, where we are looking at it from day to day, and today and yesterday and tomorrow, God sees the whole thing. He sees the end from the beginning. And as far as God is concerned, we're just in a re-run. It's just something He can already see, the whole scene, the end results, and the whole thing on out.

He knows the end from the beginning. Now there would be fantastic advantages to be able to be released from our linear timeframe references and to become, to come outside of timeframe and be able to see as God sees, the whole thing. John had that experience, the book of Revelation. He said, "I, John, was in the spirit unto the day of the Lord." God took him in the time chamber and he took him on out past the day in which we're even living. And the Lord showed to John the things that are going to be taking place on the earth after the church is taken out and the earth is undergoing the Great Tribulation period. And John saw events that are going to take place on the earth. Described the events as he saw them in this time chamber that God just released him from the timeframe, linear timeframe that we experience and took him outside of it. And John was able to see down the road and he described in the book of Revelation things that yet have not happened, but surely will happen, for God released him outside of the timeframe reference.

So God existing out of the timeframe reference knows. He knows your life. He knows the end of your life. He knows the whole score. You spend your life like a story that's already been told. It's just like watching USC play Washington today on television when they replayed the game. It's already over; it's already done. The score's already been established. You're just watching something that already happened. And that's the way God looks at your life, is like it's already happened. He knows already what the score is.

So those whom He foreknew, "those whom He foreknew, He did also predestinate. And those that he predestinated, He also chose" ( Romans 8:29-30 ). So God chose you in Christ when? After you were born and after you came forward? No, God chose you in Christ before the foundations of the world, because He is outside of the timeframe zone and He could look down and He could see the whole end. He could see your life and the whole end of your life and on out, and He sees out because time doesn't exist with God. He lives outside of time. So on the basis of this ability of being outside of the linear timeframe reference, God then made His choices. All right! He chose me! Isn't that neat?

Having that kind of wisdom, He'd never choose a loser. So the fact that God has chosen me, that automatically writes me in. I'm a winner. For what God has begun in me, He's going to finish. Now we have difficulty with the concept of pre-destination and election, chosen in Him and so forth. We have difficulty with that because we only think, and we can only think, we're limited in our thinking, to this linear timeframe reference. And that's what makes it hard to understand, "Well, how could God choose me? That isn't fair God choose me," and so forth. Oh, if He wants to choose me, that's all right. I'm not going to argue. I'm only going to rejoice. Chosen in Him.

So I spend my life like a story that's already been told. God knows the end of it. He knows the final chapter. I don't know that yet. I'm coming into it, you know, and I'm discovering the things that God has already known. Anything I ever discover is something that God has already known. I'm only discovering things that God has. I'm not discovering new truth. New truth doesn't exist. God has already known all these things. They are unfolding to me as I go along. But God... and so I love this whole concept that Moses gets into of the nature of God, the eternal nature of God from everlasting to everlasting. Outside, so our lives are as a tale that has been told.

The days of our years ( Psalms 90:10 )

Now here I am in this linear timeframe, and I'll spend seventy years in this linear timeframe, perhaps.

And if I go to eighty, it will be with great labor and sorrow; and I can be sure that I'm soon going to be cut off, and fly away ( Psalms 90:10 ),

When you get up there.

Who knows the power of your anger? even according to your fear, so is your wrath. So teach us, Lord, to number our days ( Psalms 90:11-12 ),

Now I'm living in this time zone so, God, teach me to number my days that I might really use the time that I am here to the best advantage. God has given me an allotted span of time. God has given me, in this timeframe, an allotted span of time. In this front timeframe, there's a line down here that God knows, I don't know it yet, but there's a line down here that God says that's the end of Chuck as far as his existence in the timeframe reference. God knows the day in which my soul and spirit are going to leave this body. God knows the day that I'm going to depart from this body. He already knows the day; He already knows the circumstances by which my soul and spirit will depart from the body. He already knows that. He's already made the appointment for me. It's a date down here, there's a time down here that God knows. I don't know it. I'm coming into it. I live by progressive revelation, but God already knows. He's already established. I don't know when it might be. It might be much sooner than what I'm anticipating. I may not even get to the threescore and ten. I personally don't think I will have lost anything if I don't. But God help me to use wisely each day. Lord, teach me to number my days, because I don't know when the day of opportunity of my serving God is going to come to an end. So Lord, teach me to number my days that I might incline my heart to wisdom, that I might use wisely the time that I'm here. Use it to its best advantage for God.

Oh, we waste so much precious time in front of that stupid television. An evil device that is designed to rob you of precious time, making men very shallow because it's filling their minds with emptiness. God, teach me to number my days.

that I might apply my heart to wisdom. Return, O LORD, how long? let it repent thee concerning your servants. O satisfy us early with your mercy; that we may rejoice and be glad all of our days ( Psalms 90:12-14 )

I don't know how many days I have but, God, I want to live a happy life, rejoice and be glad.

Make us glad according to the days wherein you've afflicted us, and the years wherein we have seen evil. Let thy work appear unto thy servants, and thy glory unto their children ( Psalms 90:15-16 ).

And then the prayer of Moses I think is absolutely gorgeous.

Let the beauty of the LORD our God be upon us: and establish the work of our hands upon us; yea, the work of our hands establish it ( Psalms 90:17 ).

The prayer, though, "Let the beauty of the Lord be upon my life." We used to sing a chorus years ago when I was a little kid, "Let the beauty of Jesus be seen in me. All of His wonderful passion and purity. O Thou Spirit divine. All mine nature refine, till the beauty of Jesus be seen in me."

Oh, let the beauty of the Lord our God be upon us, beauty of God might be seen in our lives and through our lives and through the works of our lives. Let God's beauty show forth to this needy world.

Shall we stand.

May God be with you and watch over you during the week and God help us that we might number our days, incline our hearts to wisdom. Use the time that God has given us this week to serve Him, to lay up for ourselves treasures in heaven. And may the Spirit of God work in your heart and life conforming you into the image of Christ, that the beauty of the Lord our God might be seen by others as you walk with Him this week. God bless you, keep His hand upon you. In Jesus' name. "

Dr. Constable's Expository Notes

1. The transitory nature of human life 90:1-12

Dr. Constable's Expository Notes

IV. BOOK 4: CHS. 90-106

Moses composed one of the psalms in this section of the Psalter (Psalms 90), and David wrote two of them (Psalms 101, 103). The remaining 14 are anonymous. Book 4 opens with a psalm attributed to Moses, and it closes with one in which Moses is the dominant figure. Prominent themes in this book include the brevity of life, Yahweh’s future reign on the earth and proper human response to that hope, and Yahweh’s creative and sustaining power. So one might think of Book 4 as the book of Moses, but perhaps a better title would be "the book of the King."

Psalms 90

The psalmist asked God to bless His people in view of life’s brevity. This "one of the most magisterial of the psalms" [Note: Brueggemann, p. 110.] has been called a communal psalm of trust.

"The psalms of trust are written for the express purpose of declaring the psalmist’s trust in God. . . . A second element of the psalms of trust or confidence is the invitation to trust issued to the community. . . . A third element of this group of psalms is the basis for trust. . . . A fourth element in the psalms of trust is petition. . . . Given the nature of the psalmist’s faith, it is not surprising that in at least two instances a fifth element enters the psalm. The worshiper makes a vow or promise to praise the Lord (Psalms 16:7; Psalms 27:6 b; Psalms 115:17-18). . . . The sixth element, and next to the declaration of trust, the most frequent component of the psalms of trust, is the interior lament. It is not a lament as such, but the remnant of one." [Note: Bullock, pp. 168-70.]

Bullock considered Psalms 115, 123-26 as other community psalms of trust. [Note: Ibid., p. 169.] The superscription attributes the authorship of this psalm to Moses (cf. Deuteronomy 33:1). It is evidently the only one he wrote that God preserved in the Psalms. The content suggests that he may have written it during the wilderness wanderings, possible at Pisgah (Deuteronomy 34). In any case, it is probably one of the oldest of the psalms if not the oldest. Brueggemann believed that this psalm was attributed to Moses but not necessarily written by him. [Note: Brueggemann, p. 110.]

"In an age which was readier than our own to reflect on mortality and judgment, this psalm was an appointed reading (with 1 Corinthians 15) at the burial of the dead: a rehearsal of the facts of death and life which, if it was harsh at such a moment, wounded to heal. In the paraphrase by Isaac Watts, ’O God, our help in ages past’, it has established itself as a prayer supremely matched to times of crisis." [Note: Kidner, Psalms 73-150, pp. 327-28.]

Dr. Constable's Expository Notes

Humans only live a short time because God judges the sin in their lives (cf. Romans 6:23). God knows even our secret sins. They do not escape Him, and He judges us with physical death for our sins.

Assuming Moses did write this psalm, it is interesting that he said the normal human life span was 70 years. He lived to be 120, Aaron was 123 when he died, and Joshua died at 110. Their long lives testify to God’s faithfulness in providing long lives to the godly, as He promised under the Mosaic Covenant.

Since our lives are comparatively short we should number our days (Psalms 90:12). Moses meant we should realize how few they are and use our time wisely (cf. Ecclesiastes 12:1-7). Notice how often Moses mentioned "our days" or the equivalent in this psalm (Psalms 90:4-6; Psalms 90:9-10; Psalms 90:12; Psalms 90:14-15).

"The pivotal point of the text, I suggest, is the goal of a ’heart of wisdom’ (Psalms 90:12)." [Note: Brueggemann, p. 111. ]

A heart of wisdom refers to discernment of Yahweh’s purposes.

Gill's Exposition of the Whole Bible

So teach us to number our days,.... Not merely to count them, how many they are, in an arithmetical way; there is no need of divine teachings for that; some few instructions from an arithmetician, and a moderate skill in arithmetic, will enable persons not only to count the years of their lives, but even how many days they have lived: nor is this to be understood of calculating or reckoning of time to come; no man can count the number of days he has to live; the number of his days, months, and years, is with the Lord; but is hid from him: the living know they shall die; but know not how long they shall live, and when they shall die: this the Lord teaches not, nor should we be solicitous to know: but rather the meaning of the petition is, that God would teach us to number our days, as if the present one was the last; for we cannot boast of tomorrow; we know not but this day, or night, our souls may be required of us: but the sense is, that God would teach us seriously to meditate on, and consider of, the shortness of our days; that they are but as a shadow, and there is no abiding; and the vanity and sinfulness of them, that so we may not desire to live here always; and the troubles and sorrows of them, which may serve to wean us from the world, and to observe how unprofitably we have spent them; which may put us upon redeeming time, and also to take notice of the goodness of God, that has followed us all our days, which may lead us to repentance, and engage us in the fear of God:

that we may apply our hearts unto wisdom; to consider our latter end, and what will become of us hereafter; which is a branch of wisdom so to do; to seek the way of salvation by Christ; to seek to Christ, the wisdom of God, for it; to fear the Lord, which is the beginning of wisdom; and to walk circumspectly, not as fools, but as wise; to all which an application of the heart is necessary; for wisdom is to be sought for heartily, and with the whole heart: and to this divine teachings are requisite, as well as to number our days; for unless a man is taught of God, and by his Spirit convinced of sin, righteousness, and judgment, he will never be concerned, in good earnest, about a future state; nor inquire the way of salvation, nor heartily apply to Christ for it: he may number his days, and consider the shortness of them, and apply his heart to folly, and not wisdom; see Isaiah 22:21.

Henry's Complete Commentary on the Bible

      12 So teach us to number our days, that we may apply our hearts unto wisdom.   13 Return, O LORD, how long? and let it repent thee concerning thy servants.   14 O satisfy us early with thy mercy; that we may rejoice and be glad all our days.   15 Make us glad according to the days wherein thou hast afflicted us, and the years wherein we have seen evil.   16 Let thy work appear unto thy servants, and thy glory unto their children.   17 And let the beauty of the LORD our God be upon us: and establish thou the work of our hands upon us; yea, the work of our hands establish thou it.

      These are the petitions of this prayer, grounded upon the foregoing meditations and acknowledgments. Is any afflicted? Let him learn thus to pray. Four things they are here directed to pray for:--

      I. For a sanctified use of the sad dispensation they were now under. Being condemned to have our days shortened, "Lord, teach us to number our days (Psalms 90:12; Psalms 90:12); Lord, give us grace duly to consider how few they are, and how little a while we have to live in this world." Note, 1. It is an excellent art rightly to number our days, so as not to be out in our calculation, as he was who counted upon many years to come when, that night, his soul was required of him. We must live under a constant apprehension of the shortness and uncertainty of life and the near approach of death and eternity. We must so number our days as to compare our work with them, and mind it accordingly with a double diligence, as those that have no time to trifle. 2. Those that would learn this arithmetic must pray for divine instruction, must go to God, and beg of him to teach them by his Spirit, to put them upon considering and to give them a good understanding. 3. We then number our days to good purpose when thereby our hearts are inclined and engaged to true wisdom, that is, to the practice of serious godliness. To be religious is to be wise; this is a thing to which it is necessary that we apply our hearts, and the matter requires and deserves a close application, to which frequent thoughts of the uncertainty of our continuance here, and the certainty of our removal hence, will very much contribute.

      II. For the turning away of God's anger from them, that though the decree had gone forth, and was past revocation, there was no remedy, but they must die in the wilderness: "Yet return, O Lord! be thou reconciled to us, and let it repent thee concerning thy servants (Psalms 90:13; Psalms 90:13); send us tidings of peace to comfort us again after these heavy tidings. How long must we look upon ourselves as under thy wrath, and when shall we have some token given us of our restoration to thy favour? We are thy servants, thy people (Isaiah 64:9); when wilt thou change thy way toward us?" In answer to this prayer, and upon their profession of repentance (Numbers 14:39; Numbers 14:40), God, in the next chapter, proceeding with the laws concerning sacrifices (Numbers 15:1-31, c.), which was a token that it repented him concerning his servants for, if the Lord had been pleased to kill them, he would not have shown them such things as these.

      III. For comfort and joy in the returns of God's favour to them, Psalms 90:14; Psalms 90:15. They pray for the mercy of God; for they pretend not to plead any merit of their own. Have mercy upon us, O God! is a prayer we are all concerned to say Amen to. Let us pray for early mercy, the seasonable communications of divine mercy, that God's tender mercies may speedily prevent us, early in the morning of our days, when we are young and flourishing, Psalms 90:6; Psalms 90:6. Let us pray for the true satisfaction and happiness which are to be had only in the favour and mercy of God, Psalms 4:6; Psalms 4:7. A gracious soul, if it may but be satisfied of God's lovingkindness, will be satisfied with it, abundantly satisfied, will take up with that, and will take up with nothing short of it. Two things are pleaded to enforce this petition for God's mercy:-- 1. That it would be a full fountain of future joys: "O satisfy us with thy mercy, not only that we may be easy and at rest within ourselves, which we can never be while we lie under thy wrath, but that we may rejoice and be glad, not only for a time, upon the first indications of thy favour, but all our days, though we are to spend them in the wilderness." With respect to those that make God their chief joy, as their joy may be full (1 John 1:4), so it may be constant, even in this vale of tears; it is their own fault if they are not glad all their days, for his mercy will furnish them with joy in tribulation and nothing can separate them from it. 2. That it would be a sufficient balance to their former griefs: "Make us glad according to the days wherein thou has afflicted us; let the days of our joy in thy favour be as many as the days of our pain for thy displeasure have been and as pleasant as those have been gloomy. Lord, thou usest to set the one over-against the other (Ecclesiastes 7:14); do so in our case. Let it suffice that we have drunk so long of the cup of trembling; now put into our hands the cup of salvation." God's people reckon the returns of God's lovingkindness a sufficient recompence for all their troubles.

      IV. For the progress of the work of God among them notwithstanding, Psalms 90:16; Psalms 90:17. 1. That he would manifest himself in carrying it on: "Let thy work appear upon thy servants; let it appear that thou hast wrought upon us, to bring us home to thyself and to fit us for thyself." God's servants cannot work for him unless he work upon them, and work in them both to will and to do; and then we may hope the operations of God's providence will be apparent for us when the operations of his grace are apparent upon us. "Let thy work appear, and in it thy glory will appear to us and those that shall come after us." In praying for God's grace God's glory must be our end; and we must therein have an eye to our children as well as to ourselves, that they also may experience God's glory appearing upon them, so as to change them into the same image, from glory to glory. Perhaps, in this prayer, they distinguish between themselves and their children, for so God distinguished in his late message to them (Numbers 14:31, Your carcases shall fall in this wilderness, but your little ones I will bring into Canaan): "Lord," say they, "let thy work appear upon us, to reform us, and bring us to a better temper, and then let thy glory appear to our children, in performing the promise to them which we have forfeited the benefit of." 2. That he would countenance and strengthen them in carrying it on, in doing their part towards it. (1.) That he would smile upon them in it: Let the beauty of the Lord our God be upon us; let it appear that God favours us. Let us have God's ordinances kept up among us and the tokens of God's presence with his ordinances; so some. We may apply this petition both to our sanctification and to our consolation. Holiness is the beauty of the Lord our God; let that be upon us in all we say and do; let the grace of God in us, and the light of our good works, make our faces to shine (that is the comeliness God puts upon us, and those are comely indeed who are so beautified), and then let divine consolations put gladness into our hearts, and a lustre upon our countenances, and that also will be the beauty of the Lord upon us, as our God. (2.) That he would prosper them in it: Establish thou the work of our hands upon us. God's working upon us (Psalms 90:16; Psalms 90:16) does not discharge us from using our utmost endeavours in serving him and working out our salvation. But, when we have done all, we must wait upon God for the success, and beg of him to prosper our handy works, to give us to compass what we aim at for his glory. We are so unworthy of divine assistance, and yet so utterly insufficient to bring any thing to pass without it, that we have need to be earnest for it and to repeat the request: Yea, the work of our hands, establish thou it, and, in order to that, establish us in it.
