Numbers 25:10-13

GOD spoke to Moses: “Phinehas son of Eleazar, son of Aaron the priest, has stopped my anger against the People of Israel. Because he was as zealous for my honor as I myself am, I didn’t kill all the People of Israel in my zeal. So tell him that I am making a Covenant-of-Peace with him. He and his descendants are joined in a covenant of eternal priesthood, because he was zealous for his God and made atonement for the People of Israel.”
