Shall vain words? - Margin, As in Hebrew words of wind; that is, words which were devoid of thought-light, trifling. This is a retort on Eliphaz. He had charged Job Job 15:2-3 with uttering only such words. Such forms of expression are common in the East. "His promise, it is only wind." "Breath, breath: all breath." Roberts.
Or what emboldeneth thee? - "What provokes or irritates thee, that thou dost answer in this manner? What have I said, that has given occasion to such a speech - a speech so severe and unkind?" The Syriac reads this, "do not afflict me any more with speeches; for if you speak any more, I will not answer you."
Vain words - Literally, words of air.
What emboldeneth thee - Thou art totally ignorant of the business; what then can induce thee to take part in this discussion?
Shall (a) vain words have an end? or what emboldeneth thee that thou answerest?
(a) Which serve for vain ostentation and for no true comfort.
Shall vain words have an end?.... Or "words of wind" (k), vain empty words, great swelling words of vanity, mere bubbles that look big, and have nothing in them; here Job retorts what Eliphaz had insinuated concerning him and his words, Job 15:2; and he intimates such worthless discourses should have an end, and a speedy one, and not be carried on to any length, they not bearing it; and wishes they were at an end, that he might hear no more of them; and suggests that it was weak and foolish in them to continue them; that if they could speak to no better purpose, it would be best to be silent:
or what emboldeneth thee that thou answerest? when men are engaged in a good cause, have truth on their side, and are furnished with arguments sufficient to defend it, this animates and emboldens them to stand up in the defence of it, and to answer their adversaries, and to reply when there is occasion; but Job could not imagine what should encourage and spirit up Eliphaz to answer again, when he had been sufficiently confuted; when his cause was bad, and he had no strong reasons to produce in the vindication of it; or "what has exasperated" or "provoked thee" (l) to make reply? here Job seems to have thought that he had said nothing that was irritating, though it is notorious he had, such were his grief and troubles; and so well assured he was of his being in the right, that the harsh and severe words and expressions he had used were not thought by him to have exceeded due bounds, such as Job 12:2.
(k) "verbis venti", Beza, Bolducius, Mercerus, Schmidt, Michaelis. (l) "quid exacerbat te", Junius & Tremellius; so Codureus, Schultens.
"Words of wind," Hebrew. He retorts upon Eliphaz his reproach (Job 15:2).
emboldeneth--literally, "What wearies you so that ye contradict?" that is, What have I said to provoke you? &c. [SCHUTTENS]. Or, as better accords with the first clause, "Wherefore do ye weary yourselves contradicting?" [UMBREIT].
End - When wilt thou put an end to these impertinent discourses? He retorts upon him his charge, Job 15:2-3.
