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.
Ye shall offer no strange incense thereon, nor burnt-offering, nor meal-offering; and ye shall pour no drink-offering thereon.
and he shall take a censer full of coals of fire from off the altar before Jehovah, and his hands full of sweet incense beaten small, and bring it within the veil:
These are the names of the sons of Aaron, the priests that were anointed, whom he consecrated to minister in the priest's office.
And Nadab and Abihu died before Jehovah, when they offered strange fire before Jehovah, in the wilderness of Sinai, and they had no children; and Eleazar and Ithamar ministered in the priest's office in the presence of Aaron their father.
But Nadab and Abihu died before their father, and had no children: therefore Eleazar and Ithamar executed the priest's office.
