Numbers 25:11-13

¹¹"Phin'ehas the son of Elea'zar, son of Aaron the priest, has turned back my wrath from the people of Israel, in that he was jealous with my jealousy among them, so that I did not consume the people of Israel in my jealousy. ¹²Therefore say, `Behold, I give to him my covenant of peace; ¹³and it shall be to him, and to his descendants after him, the covenant of a perpetual priesthood, because he was jealous for his God, and made atonement for the people of Israel.'"
