Deuteronomy 32:39-43

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: Neither is there any that can deliver out of my hand. For I lift up my hand to heaven, And say, I live for ever. If I whet my glittering sword, And mine hand take hold on judgment; I will render vengeance to mine enemies, And will reward them that hate me. I will make mine arrows drunk with blood, And my sword shall devour flesh; And that with the blood of the slain and of the captives, From the beginning of revenges upon 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 be merciful unto his land, and to his people.
