Deuteronomy 32:41-47

when I sharpen my flashing sword and begin to carry out justice, I will take revenge on my enemies and repay those who reject me. I will make my arrows drunk with blood, and my sword will devour flesh— the blood of the slaughtered and the captives, and the heads of the enemy leaders.”’ “Rejoice with him, you heavens, and let all of God’s angels worship him. Rejoice with his people, you Gentiles, and let all the angels be strengthened in him. For he will avenge the blood of his children; he will take revenge against his enemies. He will repay those who hate him and cleanse his people’s land.” So Moses came with Joshua son of Nun and recited all the words of this song to the people. When Moses had finished reciting all these words to the people of Israel, he added: “Take to heart all the words of warning I have given you today. Pass them on as a command to your children so they will obey every word of these instructions. These instructions are not empty words—they are your life! By obeying them you will enjoy a long life in the land you will occupy when you cross the Jordan River.”
