We have found out wisdom - We by dint of our own wisdom and understanding, have found out the true system of God's providence; and have been able to account for all the sufferings and tribulations of Job. Had they been able to confute Job, they would have triumphed over him in their own self-sufficiency.
God thrusteth him down, not man - This is no accidental thing that has happened to him: he is suffering under the just judgments of God, and therefore he must be the wicked man which we supposed him to be.
Lest ye should say, We have found out wisdom - That is, this has been permitted and ordered in such a manner that it might be manifest 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 entire drift 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 thrusteth him down, not man - These are the words of Elihu. The meaning is, “God only can drive Job from his position, and 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 only can give.” Accordingly Elihu, who proposes to meet the arguments of Job, makes no appeal to experience or observation; he does not ground 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 above seems to me the most simple, and most in accordance with the scope of the passage.
