Deuteronomy 32:40

38which ate the fat of their sacrifices, and drank the wine of their drink offering? Let them rise up and help you! Let them be your protection.

39“See now that I myself am he. There is no god with me. I kill and I make alive. I wound and I heal. There is no one who can deliver out of my hand.

40For I lift up my hand to heaven and declare, as I live forever,

41if I sharpen my glittering sword, my hand grasps it in judgment; I will take vengeance on my adversaries, and will repay those who hate me.

42I will make my arrows drunk with blood. My sword shall devour flesh with the blood of the slain and the captives, from the head of the leaders of the enemy.”
