Numbers 25:10-13

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