1 These also are the generations of Aaron and Moses in the day that the LORD spoke 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 who were anointed, whom he consecrated to minister in the priest's office.
4 And Nadab and Abihu died before the LORD, when they offered unholy 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 spoke 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 perform his duties, and the duties of the whole congregation before the tabernacle of meeting, to do the work of the tabernacle.
