Psalms (Author Moses, David, Solomon, Asaph, Heman, Ethan, sons of Korah, compiled by Ezra)
Chapter 58
10The righteous shall rejoice when he seeth the vengeance: he shall wash his feet in the blood of the wicked.11So that a man shall say, Verily there is a reward for the righteous: verily he is a God that judgeth in the earth.
