Psalms 58:9-11 (Judgment - He shall wash His feet in their blood)

9  Before your pots can feel the thorns, he shall take them away as with a whirlwind, both living, and in his wrath.			
10  The righteous shall rejoice when he seeth the vengeance: he shall wash his feet in the blood of the wicked.
11  So that a man shall say, Verily there is a reward for the righteous: verily he is a God that judgeth in the earth.
