Job 34:29 (ESV)

29 When he is quiet, who can condemn? When he hides his face, who can behold him, whether it be a nation or a man?

There are times when God hides his face and allows evil to continue for a prolonged period. Elihu does not try to deny this, nor does he try to explain it. He simply points out (in Job 34:29–33) that humans have no right to criticize God’s ways.
