Albert Barnes Commentary Job 32:13

"Beware lest ye say, We have found wisdom; God may vanquish him, not man:" — Job 32:13 (ASV)

Lest you should say, We have found out wisdom - That is, this has been permitted and ordered so that it might be evident that the truths which are to convince him come from God and not from man. You were not permitted to refute or convince him, for if you had been, you would have been lifted up with pride and would have attributed to yourselves what belongs to God.

This is in accordance with the main thrust of the book, which is to introduce the Almighty Himself to settle the controversy when human wisdom failed. They could not arrogate to themselves the claim that they had found out wisdom. They had been completely silenced by Job; they had no power to drive him from his positions; they could not explain the divine dealings so as to settle the great inquiry in which they had been engaged.

Elihu proposes to do it, and to do it in such a way as to show that it could be accomplished only by that wisdom which is from above.

God thrusts him down, not man - These are the words of Elihu. The meaning is, “God only can drive Job from his position, show him the truth, and humble him. The wisdom of man fails. The aged, the experienced, and the wise have been unable to meet his arguments and bring him down from the positions which he has taken. That work can be done only by God Himself, or by the wisdom which He alone can give.”

Accordingly, Elihu, who proposes to meet Job’s arguments, makes no appeal to experience or observation. He does not base what he says on the maxims of sages or the results of reflection but proposes to adduce the precepts of wisdom which God had imparted to him (Job 33:4; Job 33:6). Other interpretations have, however, been given of this verse, but the one above seems to me the most simple and most in accordance with the scope of the passage.
