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.
But thou and thy sons look ye to the priesthood. And all things that pertain to the service of the altar, and that are within the veil, shall be executed by the priests. If any stranger shall approach, he shall be slain.
Whomsoever of these I shall choose, his rod shall blossom. And I will make to cease from me the murmurings of the children of Israel, wherewith they murmur against you.
