Deuteronomy 32:35, 41-43

Vengeance is mine, and recompense, At the time when their foot shall slide: For the day of their calamity is at hand, And the things that are to come upon them shall make haste.

If I whet my glittering sword, And my hand take hold on judgment; I will render vengeance to mine adversaries, And will recompense them that hate me. I will make mine arrows drunk with blood, And my sword shall devour flesh; With the blood of the slain and the captives, From the head of the leaders of the enemy. Rejoice, O ye nations, with his people: For he will avenge the blood of his servants, And will render vengeance to his adversaries, And will make expiation for his land, for his people.
