The Lord asks Job whether he knows when the mountain goats give birth and whether he observes the calving of the does. Does he number the months they fulfill, does he know when they give birth? They crouch, bring forth their young and are free of their pains; their young thrive, grow up in the open and go out and do not return to them (vv. 1-4).
Then he asks who has let the wild donkey go free and loosed the bonds of the swift donkey, to whom he gave the desert for a home and the salt land for a dwelling. He laughs at the tumult of the city and does not hear the shouts of the driver; he ranges the mountains as his pasture and searches after every green thing (vv. 5-8). Will the wild ox be willing to serve you or spend the night at your manger? Can you bind him in the furrow with ropes, or will he harrow the valleys after you? Will you depend on him because his strength is great and will you leave your labor to him (vv. 9-12)?
The Lord speaks next of the ostrich, who flaps her wings joyfully and leaves her eggs on the ground, forgetting that a foot may crush them; she treats her young harshly because God made her forget wisdom and gave her no share of understanding. But when she rouses herself to run, she laughs at the horse and his rider (vv. 13-18). Did you give the horse his might? Did you clothe his neck with a mane? He paws in the valley, exults in his strength and goes out to meet the weapons; he laughs at fear and does not turn back from the sword. When the trumpet sounds he says: Aha! (vv. 19-25). Finally, does the hawk soar by your understanding, or does the eagle mount up at your command and make his nest on high? From there he spies out the food, and his young ones suck up blood; where the slain are, there he is (vv. 26-30).
