Numbers 25:11-13 (New International Version)

¹¹ "Phinehas son of Eleazar, the son of Aaron, the priest, has turned my anger away from the Israelites; for he was as zealous as I am for my honor among them, so that in my zeal I did not put an end to them. ¹² Therefore tell him I am making my covenant of peace with him. ¹³ He and his descendants will have a covenant of a lasting priesthood, because he was zealous for the honor of his God and made atonement for the Israelites."
