Deuteronomy 32:39-43

“See now that I myself am he! There is no god besides me. I put to death and I bring to life, I have wounded and I will heal, and no one can deliver out of my hand. I lift my hand to heaven and solemnly swear: As surely as I live forever, when I sharpen my flashing sword and my hand grasps it in judgment, I will take vengeance on my adversaries and repay those who hate me. I 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.” Rejoice, you nations, with his people, for he will avenge the blood of his servants; he will take vengeance on his enemies and make atonement for his land and people.
