And bring thou near unto thee Aaron thy brother, and his sons with him, from among the children of Israel, that he may minister unto me in the priest's office, even Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.
to be a memorial unto the children of Israel, to the end that no stranger, which is not of the seed of Aaron, come near to burn incense before the LORD; that he be not as Korah, and as his company: as the LORD spake unto him by the hand of Moses.
and he spake unto Korah and unto all his company, saying, In the morning the LORD will shew who are his, and who is holy, and will cause him to come near unto him: even him whom he shall choose will he cause to come near unto him.
And thou and thy sons with thee shall keep your priesthood for every thing of the altar, and for that within the veil; and ye shall serve: I give you the priesthood as a service of gift: and the stranger that cometh nigh shall be put to death.
