Deuteronomy 32:41-43

41when I sharpen my flashing sword and begin to carry out justice, I will take revenge on my enemies and repay those who reject me.

42I 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.”’

43“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.”
