Bridgeway Bible Commentary

Control of the animal world (38:39-39:30)

The pressure on Job increases as God continues with his unanswerable questions. From the natural world in general, God moves to the animal world. He draws Job’s attention to animals that sometimes appear to have no purpose so far as human life is concerned, but are still part of God’s ordering of the world.
God asks Job if he is able to order nature by providing wild animals with food (39-41), while protecting timid animals when they give birth and care for their young (39:1-4). God gives freedom to the wild ass, but at the same time controls the animal and its habitat according to his ordering of nature. Can Job do this (5-8)? Or can Job make a wild ox work like a domestic ox, when God has given the wild ox an instinct that makes it impossible to tame (9-12)?
Some things in God’s creation are puzzling to humans. For example, it appears as if the ostrich neglects her eggs and has no concern for her young, because when she is frightened she runs away and leaves them. People may not understand why the ostrich behaves as it does, but God has given each animal its own particular instinct as he sees fit (13-18). God made the horse with an instinct to be trained. This is impressed upon Job with a description of the spectacular yet fearsome sight of war horses in battle (19-25).
Hawks and eagles make their nests in higher places than other birds, but they are not disadvantaged in looking for food. This is because of their remarkable eyesight, which enables them to see the tiniest objects from a great distance. Can Job compete with a Creator whose wisdom foresaw even the smallest detail (26-30)?

Coffman's Commentaries on the Bible

QUESTIONS REGARDING THE WILD-ASS AND THE WILD-OX

"Who hath sent out the wild-ass free? Or who hath loosed the bands of the wild-ass, Whose home I have made the wilderness, And the salt land his dwelling place? He scorneth the tumult of the city, Neither heareth he the shoutings of the driver. The range of the mountains is his pasture, And he searcheth after every green thing. Will the wild-ox be content to serve thee? Or will he abide by thy crib? Canst thou bind the wild-ox with his band in the furrow? Or will he harrow the valleys after thee? Wilt thou trust him because his strength is great? Or wilt thou leave to him thy labor? Wilt thou confide in him, that he will bring home thy seed, And gather the grain of thy threshing floor?"

The animals mentioned here are the wild-ass, which is, "The onager of central Asia,"Britannica World Language Dictionary (New York: Funk and Wagnalls Company, 1959), Vol. 1, p. 882. and the wild-ox, identified by Pope in the Anchor Bible as, "the buffalo."The Anchor Bible (Garden City, New York: Doubleday and Company, 1982), Job, p. 257.

The wild-ass, of course, is similar to the common donkey; and the mystery of these animals in some particulars is still incredibly arcane. Why, for example, has it been impossible to domesticate the buffalo? And regarding the ass, why cannot mules be produced by the breeding of the female donkey with a stallion? whereas, they are produced only by the breeding of mares with the male ass. We mention these things merely to suggest that, although men have learned many things, there are yet many incomprehensible mysteries in the natural creation that surrounds us.

Barnes' Notes on the Whole Bible

The range of the mountains is his pasture - The word rendered “range” יתור yâthûr, means properly a “searching out,” and then that which is obtained by search. The word “range” expresses the idea with sufficient exactness. The usual range of the wild ass is the mountains. Pallas, who has given a full description of the habits of the Onager, or wild ass, states, that it, especially loves desolate hills as its abode. “Acts of the Society of Sciences of Petersburg,” for the year 1777.

Smith's Bible Commentary

Chapter 39

Do you know the time when the wild goats of the rock bring forth? can you mark when the hinds calve? Can you number the months that they fulfil? [Do you know how long their pregnancies are?] or do you know the time when they bring forth? They bow themselves, they bring their young ones, and they cast out their sorrows. Can you actually harness a unicorn to plow in your field and to do your work, to bring in your harvest? Did you paint the beautiful wings on the peacocks? or the feathers of the ostrich? And this dumb ostrich that leaves her eggs in the earth, warms them in the dust, and forgets that a foot might crush them, or that the wild beast might break them in. She's hardened against her young ones, as though they were not hers: her labor is in vain without fear; Because God has deprived her of wisdom, neither hath he imparted to her understanding ( Job 39:1-3 , Job 39:10 , Job 39:12-17 ).

Now some birds have tremendous instinctive abilities: who put it in the mind of the golden plover to fly from Alaska to the Aleutians Islands in the springtime in order that they might hatch their eggs and raise their babies in Alaska in the springtime? Who put it in the mind of the plover to fly 2,000 miles over uncharted oceans and land up there in the Aleutian Islands? And then after they have their little ones, and as winter is approaching, the little golden plover turns around and flies back to Hawaii. Who guides it? Who's given it its instinctive guidance system that it can fly over the 2,000 miles of ocean nonstop and land by careful navigation there in Hawaii, even though it may be blown by crosswinds of up to 100 miles an hour and be blown off of course, yet find it's way to Hawaii? Well, you say it remembered the way that it came. Well, then who guides the kids who are left behind, who don't take off for Hawaii until two weeks after their parents have left? And they've never been to Hawaii.

God is just saying to Job, "Hey, Job, who has done all of these things? You know, you think you're so smart, go ahead and see how far you can get in doing these things." Now the ostrich, it lays its eggs, it doesn't worry about, you know, someone coming along and stepping on the sand and cracking the egg because God has hid wisdom from it. He's just let it be dumb, not care about the egg, whether it will hatch or not. He's hardened her against her young ones. And yet with some animals, there is very strong mother instincts. Then God talks about the horse with its tremendous strength and the excitement of the horse in battle and so forth. Who created this excitement within the horse?

Does the hawk fly by wisdom, and stretch forth her wings toward the south? Does the eagle mount up at your command, and makes her nest on high? ( Job 39:26-27 )

Who gave the eagle that instinct to build the nest way up on the cliff? Did you order that?

She dwells and abides on the rocks, upon the crags of the rocks, and in the strong place. And from there she seeks her prey, and her eyes behold very far off. Her young ones also suck up blood: and where the slain are, there is she ( Job 39:28-30 ). "

Gill's Exposition of the Whole Bible

The range of the mountains [is] his pasture,.... It ranges about the mountains for food; it looks about for it, as the word signifies, and tries first one place and then another to get some, it having short commons there;

and he searcheth after every green thing; herb or plant, be it what it will that is green, it seeks after; and which being scarce in deserts and mountains, it searches about for and feeds upon it, wherever it can find it; grass being the peculiar food of these creatures, see Job 6:5; and which is observed by naturalists x.

Henry's Complete Commentary on the Bible

      1 Knowest thou the time when the wild goats of the rock bring forth? or canst thou mark when the hinds do calve?   2 Canst thou number the months that they fulfil? or knowest thou the time when they bring forth?   3 They bow themselves, they bring forth their young ones, they cast out their sorrows.   4 Their young ones are in good liking, they grow up with corn; they go forth, and return not unto them.   5 Who hath sent out the wild ass free? or who hath loosed the bands of the wild ass?   6 Whose house I have made the wilderness, and the barren land his dwellings.   7 He scorneth the multitude of the city, neither regardeth he the crying of the driver.   8 The range of the mountains is his pasture, and he searcheth after every green thing.   9 Will the unicorn be willing to serve thee, or abide by thy crib?   10 Canst thou bind the unicorn with his band in the furrow? or will he harrow the valleys after thee?   11 Wilt thou trust him, because his strength is great? or wilt thou leave thy labour to him?   12 Wilt thou believe him, that he will bring home thy seed, and gather it into thy barn?

      God here shows Job what little acquaintance he had with the untamed creatures that run wild in the deserts and live at large, but are the care of the divine Providence. As,

      I. The wild goats and the hinds. That which is taken notice of concerning them is the bringing forth and bringing up of their young ones. For, as every individual is fed, so every species of animals is preserved, by the care of the divine Providence, and, for aught we know, none extinct to this day. Observe here, 1. Concerning the production of their young, (1.) Man is wholly ignorant of the time when they bring forth, Job 39:1; Job 39:2. Shall we pretend to tell what is in the womb of Providence, or what a day will bring forth, who know not the time of the pregnancy of a hind or a wild goat? (2.) Though they bring forth their young with a great deal of difficulty and sorrow, and have no assistance from man, yet, by the good providence of God, their young ones are safely produced, and their sorrows cast out and forgotten, Job 39:3; Job 39:3. Some think it is intimated (Psalms 29:9) that God by thunder helps the hinds in calving. Let it be observed, for the comfort of women in labour, that God helps even the hinds to bring forth their young; and shall he not much more succour them, and save them in child-bearing, who are his children in covenant with him? 2. Concerning the growth of their young, (Job 39:4; Job 39:4): They are in good liking; though they are brought forth in sorrow, after their dams have suckled them awhile they shift for themselves in the corn-fields, and are no more burdensome to them, which is an example to children, when they have grown up, not to be always hanging upon their parents and craving from them, but to put forth themselves to get their own livelihood and to requite their parents.

      II. The wild ass, a creature we frequently read of in Scripture, some say untameable. Man is said to be born as the wild ass's colt, so hard to be governed. Two things Providence has allotted to the wild ass:-- 1. An unbounded liberty (Job 39:5; Job 39:5): Who but God has sent out the wild ass free? He has given a disposition to it, and therefore a dispensation for it. The tame ass is bound to labour; the wild ass has no bonds on him. Note, Freedom from service, and liberty to range at pleasure, are but the privileges of a wild ass. It is a pity that any of the children of men should covet such a liberty, or value themselves on it. It is better to labour and be good for something than ramble and be good for nothing. But if, among men, Providence sets some at liberty and suffers them to live at ease, while others are doomed to servitude, we must not marvel at the matter: it is so among the brute-creatures. 2. An unenclosed lodging (Job 39:6; Job 39:6): Whose house I have made the wilderness, where he has room enough to traverse his ways, and snuff up the wind at his pleasure, as the wild ass is said to do (Jeremiah 2:24), as if he had to live upon the air, for it is the barren land that is his dwelling. Observe, The tame ass, that labours, and is serviceable to man, has his master's crib to go to both for shelter and food, and lives in a fruitful land: but the wild ass, that will have his liberty, must have it in a barren land. He that will not labour, let him not eat. He that will shall eat the labour of his hands, and have also to give to him that needs. Jacob, the shepherd, has good red pottage to spare, when Esau, a sportsman, is ready to perish for hunger. A further description of the liberty and livelihood of the wild ass we have, Job 39:7; Job 39:8. (1.) He has no owner, nor will he be in subjection: He scorns the multitude of the city. If they attempt to take him, and in order to that surround him with a multitude, he will soon get clear of them, and the crying of the driver is nothing to him. He laughs at those that live in the tumult and bustle of cities (so bishop Patrick), thinking himself happier in the wilderness; and opinion is the rate of things. (2.) Having no owner, he has no feeder, nor is any provision made for him, but he must shift for himself: The range of the mountains is his pasture, and a bare pasture it is; there he searches after here and there a green thing, as he can find it and pick it up; whereas the labouring asses have green things in plenty, without their searching for them. From the untameableness of this and other creatures we may infer how unfit we are to give law to Providence, who cannot give law even to a wild ass's colt.

      III. The unicorn--rhem, a strong creature (Numbers 23:22), a stately proud creature, Psalms 112:10. He is able to serve, but not willing; and God here challenges Job to force him to it. Job expected every thing should be just as he would have it. "Since thou dost pretend" (says God) "to bring every thing beneath thy sway, begin with the unicorn, and try thy skill upon him. Now that thy oxen and asses are all gone, try whether he will be willing to serve thee in their stead (Job 39:9; Job 39:9) and whether he will be content with the provision thou usedst to make for them: Will he abide by thy crib? No;" 1. "Thou canst not tame him, nor bind him with his band, nor set him to draw the harrow," Job 39:10; Job 39:10. There are creatures that are willing to serve man, that seem to take a pleasure in serving him, and to have a love for their masters; but there are such as will never be brought to serve him, which is the effect of sin. Man has revolted from his subjection to his Maker, and is therefore justly punished with the revolt of the inferior creatures from their subjection to him; and yet, as an instance of God's good-will to man, there are some that are still serviceable to him. Though the wild bull (which some think is meant here by the unicorn) will not serve him, nor submit to his hand in the furrows, yet there are tame bullocks that will, and other animals that are not feræ naturæ--of a wild nature, in whom man may have a property, for whom he provides, and to whose service he is entitled. Lord, what is man, that thou art thus mindful of him? 2. "Thou darest not trust him; though his strength is great, yet thou wilt not leave thy labour to him, as thou dost with thy asses or oxen, which a little child may lead or drive, leaving to them all the pains. Thou wilt never depend upon the wild bull, as likely to come to thy harvest-work, much less to go through it, to bring home thy seed and gather it into thy barn," Job 39:11; Job 39:12. And, because he will not serve about the corn, he is not so well fed as the tame ox, whose mouth was not to be muzzled in treading out the corn; but therefore he will not draw the plough, because he that made him never designed him for it. A disposition to labour is as much the gift of God as an ability for it; and it is a great mercy if, where God gives strength for service, he gives a heart; it is what we should pray for, and reason ourselves into, which the brutes cannot do; for, as among beasts, so among men, those may justly be reckoned wild and abandoned to the deserts who have no mind either to take pains or to do good.
