To Aaron and to his sons, to whom they are delivered by the children of Israel. But thou shalt appoint Aaron and his sons over the service of priesthood. The stranger that approacheth to minister shall be put to death.
And the Lord said to Aaron: Thou, and thy sons, and thy father's house with thee shall bear the iniquity of the sanctuary. And thou and thy sons with thee shall bear the sins of your priesthood.
