And they shall be upon Aaron, and upon his sons, when they enter 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 to his seed after him.
Therefore thou and thy sons with thee shall keep your priest's office for every thing of the altar, and within the vail; and ye shall serve: I have given your priest's office to you as a service of gift: and the stranger that cometh nigh shall be put to death.
But those that encamp before the tabernacle towards 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 cometh nigh shall be put to death.
