Job 16:18-21

Job cries to the avenger of blood to avenge his innocence. He is a martyr, and feels that his blood must cry for vengeance (Genesis 4:10 *, Revelation 6:10). Job arrives at the astounding thought that God will be his avenger, though it is God that slays him. We have noticed how in Job's bitter complaint against God, the thought that the God, who had loved him in the past, will one day turn to him once more, had again and again broken through (Job 7:8; Job 7:21; Job 14:13). Job now sets the God of the past and the future against the God of the present, one side of God against another, God against Himself (Job 16:21). God is his witness (Job 16:19). Davidson translates advocate and says, There was no difference between advocate and witness in the Hebrew courts, the part of a witness being to testify on behalf of one and see justice done him.
