Deuteronomy 32:42-44

42 My arrows will drip with their blood, and my sword will kill all who oppose me. I will spare no one who fights against me; even the wounded and prisoners will die.'

43 "Nations, you must praise the LORD's people--- he punishes all who kill them. He takes revenge on his enemies and forgives the sins of his people."

44 Moses and Joshua son of Nun recited this song, so that the people of Israel could hear it.
