Behold, in this thou art not just: I will answer thee, that God is greater than man.

Wesley's Notes

33:12 Not just - Thou art in the wrong. Greater - Not only in power and majesty, but also in justice, and wisdom, and goodness, and therefore thou dost foolishly, in censuring his judgments, thou castest off that awe and reverence which thou shouldest constantly maintain towards thy sovereign Lord.

Jamieson-Fausset-Brown Bible Commentary

12. in this-view of God and His government. It cannot be that God should jealously "watch" man, though "spotless," as an "enemy," or as one afraid of him as an equal. For "God is greater than man!" There must be sin in man, even though he be no hypocrite, which needs correction by suffering for the sufferer's good.

Matthew Henry's Concise Commentary

33:8-13 Elihu charges Job with reflecting upon the justice and goodness of God. When we hear any thing said to God's dishonour, we ought to bear our testimony against it. Job had represented God as severe in marking what he did amiss. Elihu urges that he had spoken wrong, and that he ought to humble himself before God, and by repentance to unsay it. God is not accountable to us. It is unreasonable for weak, sinful creatures, to strive with a God of infinite wisdom, power, and goodness. He acts with perfect justice, wisdom, and goodness, where we cannot perceive it.
