Deuteronomy 32:39-43

“Now you will see that I am the one God! There is no god but me. I send life and death; I can hurt, and I can heal. No one can escape from me. I raise my hand toward heaven and make this promise: As surely as I live forever, I will sharpen my flashing sword, and I will take it in my hand to judge. I will punish my enemies and pay back those who hate me. My arrows will be covered with their blood; my sword will eat their flesh. The blood will flow from those who are killed and the captives. The heads of the enemy leaders will be cut off.” Be happy, nations, with his people, because he will repay you for the blood of his servants. He will punish his enemies, and he will remove the sin of his land and people.
