Deuteronomy 32:40-42

40I lift up my hand to heaven and I make this strong promise: “I promise you this, as surely as I live for ever:

41I will make my sword very sharp. It will move like lightning as I hold it in my hand. I will punish my enemies as they deserve. I will pay back everyone who hates me.

42My arrows will have blood all over them. My sword will cut into the bodies of my enemies. Everyone that I take hold of will die. I will cut off the heads of their leaders.” ’
