22:21-30 The answer of Eliphaz wrongly implied that Job had hitherto not known God, and that prosperity in this life would follow his sincere conversion. The counsel Eliphaz here gives is good, though, as to Job, it was built upon a false supposition that he was a stranger and enemy to God. Let us beware of slandering our brethren; and if it be our lot to suffer in this manner, let us remember how Job was treated; yea, how Jesus was reviled, that we may be patient. Let us examine whether there may not be some colour for the slander, and walk watchfully, so as to be clear of all appearances of evil.

The irony is strikingly exhibited in Eliphaz unconsciously uttering words which exactly answer to what happened at last: he and the other two were "delivered" by God accepting the intercession of Job for them (Job 42:7, 8).
