And they shall be on Aaron, and on his sons, when they come in to the tabernacle of the congregation, or when they come near to the altar to minister in the holy place; that they bear not iniquity, and die: it shall be a statute for ever to him and his seed after him.
Therefore you and your sons with you shall keep your priest's office for everything of the altar, and within the veil; and you shall serve: I have given your priest's office to you as a service of gift: and the stranger that comes near shall be put to death.
But those that encamp before the tabernacle toward the east, even before the tabernacle of the congregation eastward, shall be Moses, and Aaron and his sons, keeping the charge of the sanctuary for the charge of the children of Israel; and the stranger that comes near shall be put to death.
