Numbers 25:10-13

Then the LORD spoke to Moses, saying, “Phinehas the son of Eleazar, the son of Aaron the priest, has turned away My wrath from the sons of Israel in that he was jealous with My jealousy among them, so that I did not destroy the sons of Israel in My jealousy. Therefore say, ‘Behold, I give him My covenant of peace; and it shall be for him and his descendants after him, a covenant of a perpetual priesthood, because he was jealous for his God and made atonement for the sons of Israel.’ ”
