Deuteronomy 32:35-41

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. For Jehovah will judge his people, And repent himself for his servants; When he seeth that their power is gone, And there is none remaining, shut up or left at large. And he will say, Where are their gods, The rock in which they took refuge; Which did eat the fat of their sacrifices, And drank the wine of their drink-offering? Let them rise up and help you, Let them be your protection. See now that I, even I, am he, And there is no god with me: I kill, and I make alive; I wound, and I heal; And there is none that can deliver out of my hand. For I lift up my hand to heaven, And say, As I live for ever, 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.
