Deuteronomy 32:40-42

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

41 if 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.

42 I 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.”
