Deuteronomy 32:40-42

40 [39] (vi) “‘For I lift up my hand to heaven and swear, “As surely as I am alive forever,

41 if I sharpen my flashing sword and set my hand to judgment, I will render vengeance to my foes, repay those who hate me.

42 I will make my arrows drunk with blood, my sword will devour flesh — the blood of the slain and the captives, flesh from the wild-haired heads of the enemy.”’
