Deuteronomy 32:42-44

42 I will make my arrows drunk with blood and my sword shall devour flesh, in the blood of the slain and of the captives of the heads, in revenge as an enemy.

43 Rejoice, O ye Gentiles, [with] his people, for he will avenge the blood of his servants and will render vengeance to his enemies and will reconcile his land, to his people.

44 And Moses came and spoke all the words of this song in the ears of the people, he, and Hosea, the son of Nun.
