Deuteronomy 32:41-47

I will sharpen my flashing sword, and I will take it in my hand to judge. I will punish my enemies and pay back those who hate me. My arrows will be covered with their blood; my sword will eat their flesh. The blood will flow from those who are killed and the captives. The heads of the enemy leaders will be cut off.” Be happy, nations, with his people, because he will repay you for the blood of his servants. He will punish his enemies, and he will remove the sin of his land and people. Moses came with Joshua son of Nun, and they spoke all the words of this song for the people to hear. When Moses finished speaking these words to all Israel, he said to them: “Pay careful attention to all the words I have said to you today, and command your children to obey carefully everything in these teachings. These should not be unimportant words for you, but rather they mean life for you! By these words you will live a long time in the land you are crossing the Jordan River to take as your own.”
