Deuteronomy 32:40-42

40For I raise up my hand to heaven, and say, ‘As surely as I live forever,

41I will sharpen my lightning-like sword, and my hand will grasp hold of the weapon of judgment; I will execute vengeance on my foes, and repay those who hate me!

42I will make my arrows drunk with blood, and my sword will devour flesh – the blood of the slaughtered and captured, the chief of the enemy’s leaders!’”
