Deuteronomy 32:40-42

40 I raise my hand to heaven and declare: As surely as I live forever,

41 when I sharpen my flashing sword, and my hand takes hold of judgment, I will take vengeance on my adversaries and repay those who hate me.

42 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.” [18]
