Adam Clarke Bible Commentary
God hath deprived her of wisdom - Of this foolishness we have an account from the ancients; and here follow two instances:
1. It covers its head in the reeds, and thinks itself all out of sight because itself cannot see. So Claudian: -
- 'Stat lumine clauso
Ridendum revoluta caput: creditque latere
Quad non ipsa videt.'
2. They who hunt them draw the skin of an ostrich's neck on one hand, which proves a sufficient lure to take them with the other. They have so little brain that Heliogabalus had six hundred heads for his supper. Here we may observe, that our judicious as well as sublime author just touches the great points of distinction in each creature, and then hastens to another. A description is exact when you cannot add but what is common to another thing; nor withdraw, but something peculiarly belonging to the thing described. A likeness is lost in too much description, as a meaning is often in too much illustration." - Dr. Young.
Jamieson-Fausset-Brown Bible Commentary
wisdom--such as God gives to other animals, and to man (Job 35:11). The Arab proverb is, "foolish as an ostrich." Yet her very seeming want of wisdom is not without wise design of God, though man cannot see it; just as in the trials of the godly, which seem so unreasonable to Job, there lies hid a wise design.
John Gill Bible Commentary
Because God hath deprived her of wisdom,.... Or "made her to forget" (d) what she had; an instance of her forgetfulness is mentioned Job 39:15; and so Leo Africanus (e) says of it, that it is of a very short memory, and presently forgets the place where its eggs are laid;
neither hath he imparted to her understanding; many instances are given of its stupidity by historians, as that it will take anything that is offered to it to eat, stones, iron, &c. (f); that it will thrust its head and neck into a thicket, fancying: it is hid and covered, and that none can see it; which Pliny (g) remarks as an instance of its foolishness; though Diodorus Siculus (h) takes this to be a point of prudence, for the preservation of those parts of it which are weakest. Strabo gives (i) another instance of its stupidity, its being so easily deceived by sportsmen, who, by putting the skin of an ostrich on their hands, and reaching out fruits or seeds to it, it will receive them of them, and be taken. Others observe the smallness of their heads, and so of their brains, as an argument of their want of understanding; and it has been remarked, as a proof of their having but few brains, that Heliogabalus, the Roman emperor, had six hundred heads of ostriches dressed at once for his supper, for the sake of their brains (k).
