Deuteronomy 32:42-44

42 I will make my arrows drunk with blood, my sword will devour flesh — the blood of the slain and the captives, flesh from the wild-haired heads of the enemy.”’

43 “Sing out, you nations, about his people! For he will avenge the blood of his servants. He will render vengeance to his adversaries and make atonement for the land of his people.”

44 [43] (vii) Moshe came and proclaimed all the words of this song in the hearing of the people and of Hoshea the son of Nun.
