“The righteous shall reioyce when he seeth the vengeance: he shall wash his feete in the blood of the wicked.”
1611 King James Version (KJV)
58:10 Rejoice - For the blessed effects of it; the vindication of God's honour, and the deliverance of himself and of all good men. Wash - There shall be so great a slaughter of his enemies that he might, if he pleased, wash his feet in their blood.
