Job 13:8

"Do you pretend that you do not want to judge? Can you still hide, and not agree that I have spoken of you in truth?

"If he follows your traces," Job says. Therefore you, who speak so now would have not spoken so, if you were directly involved in the case that is judged. That is, if you were in my place and God were judging your matters with severity, you would have not judged my words as you do now. Or, to say things in a different manner, you, who speak so, would have not been judges of my words. In fact, Job says, even if you speak more, and you do everything to speak in God's favor, he will not confound you any less and will ask you for explanations.

Will ye take His person? will ye strive to judge for God? For when foolish men behold the doings of the wise, they all seem to them to be worthy of blame; who, forgetting their own emptiness and deficiency, pass judgment on the concerns of others the more eagerly, in proportion as they are more deeply ignorant of their own. But on the other hand, when the righteous reprove the deeds of the wicked, ever conscious of their own weakness, they administer reproof, though in launching forth against them outwardly, yet in sympathizing with them inwardly; in that it belongs to Him alone to scrutinize the sins of men without fellow-feeling, Who by the omnipotence of His nature knows not to commit sin. Therefore, as the friends of blessed Job had so reproved his deeds as if they had nothing in themselves to be reproved, it is well said in this place, Will ye take His face? Will ye strive to judge for God? For to 'take the face of God' is to assume His authority in the act of judging; and he as it were 'strives to judge for God,' who when he reproves the several weak points in another, does not feel weak in himself within from fellow-feeling.
