Adam Clarke on Job 32:13

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.
