Job 25:6

By contrast, man is far smaller than the moon or the stars, and is like. maggot or worm in God's sight. This entire speech seems designed to humiliate Job. Therefore, no man should ever be so brash to assert his innocence before God. "Certainly no 'worm' should argue with God about his integrity or seek self-vindication" (Strauss p. 253). Job would agree that God is great and that man is to be humble. Yet, man isn't worthless (Psalms 8:3ff). This speech doesn't help Job, for he is seeking vindication and not purification. He is already innocent.
