The righteous shall rejoice when he seeth the vengeance: he shall wash his feet in the blood of the wicked.
The righteous will rejoice when they see vengeance fall and judgment defeat the wicked. The washing of feet in the blood of the wicked expresses the completeness of that vengeance. That rejoicing is not delight in the calamity and anguish of others nor from personal resentment, but joy because God's cause triumphs, justice is vindicated, and it is seen that the righteous are rewarded and that God judges the earth. The words are prophecy of what will come upon those who merit punishment, not a prayer arising from personal resentment. This judgment takes place at the end of the thousand years, when the unjust are raised and punished in the lake of fire, which is the burning earth, and the righteous see it from the New Jerusalem and go out to look upon it.
