Doth the wild ass bray when he hath grass? - On the habits of the wild ass, see the notes at Job 11:12. The meaning of Job here is, that he did not complain without reason; and this he illustrates by the fact that the wild animal that had a plentiful supply of food would be gentle and calm, and that when its bray was heard it was proof that it was suffering. So Job says that there was a reason for his complaining. He was suffering; and perhaps he means that his complaint was just as natural, and just as innocent, as the braying of the ass for its food. He should have remembered however, that he was endowed with reason, and that he was bound to evince a different spirit from the brute creation.
Or loweth the ox over his fodder? - That is, the ox is satisfied and uncomplaining when his needs are supplied. The fact that he lows is proof that he is in distress, or there is a reason for it. So Job says that his complaints were proof that he was in distress, and that there was a reason for his language of complaint.

Doth the wild ass - פרא pere, translated onager, by the Vulgate, from the ονος αγριος of the Septuagint, which we properly enough, translate wild ass. It is the same with the tame ass; only in a wild state it grows to a larger size, is stronger, and more fleet. The meaning of Job appears to be this: You condemn me for complaining; do I complain without a cause? The wild ass will not bray, and the ox will not low, unless in want. If they have plenty of provender, they are silent. Were I at rest, at ease, and happy, I would not complain.

Doth the (d) wild ass bray when he hath grass? or loweth the ox over his fodder?
(d) Do you think that I cry without cause, seeing the brute beasts do not complain when they have what they want.

Doth the wild ass bray when he hath grass? or loweth the ox over his fodder? No, they neither of them do, when the one is in a good pasture, and the other has a sufficiency of provender; but when they are in want of food, the one will bray, and the other will low, which are tones peculiar to those creatures, and express their mournful complaints; wherefore Job suggests, that should he make no moan and complaint in his sorrowful circumstances, he should be more stupid and senseless than those brute creatures: and he may have some respect to the different circumstances of himself and his friends; he himself, when he was in prosperity, made no complaints, as the wild ass brays not, and the ox lows not, when they have both food enough; but now, being in distress, he could not but utter his sorrow and trouble, as those creatures when in lack of food; and this may serve as an answer to his different conduct now and formerly, objected to him, Job 4:3; and so his friends; they lived in great tranquillity and prosperity, as Aben Ezra observes, and roared and grieved not, which doubtless they would, were they in the same circumstances he was; though it became them, as things were, to have uttered words of condolence to their friend in distress, instead of sharp reproofs and hard censures.

Neither wild animals, as the wild ass, nor tame, as the ox, are dissatisfied when well-supplied with food. The braying of the one and the lowing of the other prove distress and want of palatable food. So, Job argues, if he complains, it is not without cause; namely, his pains, which are, as it were, disgusting food, which God feeds him with (end of Job 6:7). But he should have remembered a rational being should evince a better spirit than the brute.

5 Doth the wild ass bray at fresh grass?
Or loweth an ox over good fodder?
6 Is that which is tasteless eaten unsalted?
Or is there flavour in the white of an egg?
7 That which my soul refused to touch,
The same is as my loathsome food.
The meaning of the first two figures is: He would not complain, if there were really no cause for it; of the two others: It is not to be expected that he should smile at his suffering, and enjoy it as delicate food. על־בּלילו I have translated "over good fodder," for בּליל is mixed fodder of different kinds of grain, farrago. "Without salt" is virtually adjective to תּפל, insipid, tasteless. What is without salt one does not relish, and there is no flavour in the slime of the yolk of an egg, i.e., the white of an egg (Targ.),
(Note: Saadia compares b. Aboda zara, 40, a, where it is given as a mark of the purity of the eggs in the roe of fish: מבפנים וחלמון מב מבחוץ חלבון, when the white is outside and the yellow within.)
or in the slime of purslain (according to Chalmetho in the Peschito, Arab. ḥamqâ), fatua = purslain), which is less probable on account of ריר (slime, not: broth): there is no flavour so that it can be enjoyed. Thus is it with his sufferings. Those things which he before inwardly detested (dirt and dust of leprosy) are now sicut fastidiosa cibi mei, i.e., as loathsome food which he must eat. The first clause, Job 6:7, must be taken as an elliptic relative clause forming the subject: vid., Ges. 123, 3, c. Such disagreeable counsel is now like his unclean, disgusting diet. Eliphaz desires him to take them as agreeable. דּוי in כּדרי is taken by Ges. Ew., Hahn, Schlottm., Olsh. (165, b), as constr. from דּוי, sickness, filth; but דּוי, as plur. from דּוה, sick, unclean (especially of female menstruation, Isaiah 30:22), as Heiligst. among modern commentators explains it, is far more suitable. Hitz. (as anonym. reviewer of Ewald's Job in the liter. Centralblatt) translates: they (my sufferings) are the morsels of my food; but the explanation of המּה is not correct, nor is it necessary to go to the Arabic for an explanation of כּדרי. It is also unnecessary, with Bttcher, to read כּדוי (such is my food in accordance with my disease); Job does not here speak of his diet as an invalid.

Doth, &c. - Even the brute beasts, when they have convenient food, are quiet and contented. So it is no wonder that you complain not, who live in ease and prosperity, any more than I did, when I wanted nothing.
