KJV(i)
1 These also are the generations of Aaron and Moses in the day that the LORD spake with Moses in mount Sinai.
2 And these are the names of the sons of Aaron; Nadab the firstborn, and Abihu, Eleazar, and Ithamar.
3 These are the names of the sons of Aaron, the priests which were anointed, whom he consecrated to minister in the priest's office.
4 And Nadab and Abihu died before the LORD, when they offered strange fire before the LORD, in the wilderness of Sinai, and they had no children: and Eleazar and Ithamar ministered in the priest's office in the sight of Aaron their father.
5 And the LORD spake unto Moses, saying,
6 Bring the tribe of Levi near, and present them before Aaron the priest, that they may minister unto him.
7 And they shall keep his charge, and the charge of the whole congregation before the tabernacle of the congregation, to do the service of the tabernacle.
8 And they shall keep all the instruments of the tabernacle of the congregation, and the charge of the children of Israel, to do the service of the tabernacle.
9 And thou shalt give the Levites unto Aaron and to his sons: they are wholly given unto him out of the children of Israel.
10 And thou shalt appoint Aaron and his sons, and they shall wait on their priest's office: and the stranger that cometh nigh shall be put to death.
