Deuteronomy 32:41-47

41when I sharpen my flashing sword, and my hand takes hold of judgment, I will take vengeance on my adversaries and repay those who hate me.

42I will make my arrows drunk with blood while my sword devours flesh — the blood of the slain and the captives, the heads of the enemy leaders.”

43Rejoice, you nations, concerning his people, for he will avenge the blood of his servants. He will take vengeance on his adversaries; he will purify his land and his people.

44Moses came with Joshua son of Nun and recited all the words of this song in the presence of the people.

45After Moses finished reciting all these words to all Israel,

46he said to them, “Take to heart all these words I am giving as a warning to you today, so that you may command your children to follow all the words of this law carefully.

47For they are not meaningless words to you but they are your life, and by them you will live long in the land you are crossing the Jordan to possess.”
