2 These are the names of the sons of Aaron: Nadab the firstborn, Abihu, Eleazar, and Ithamar.
3 These are the names of the sons of Aaron, the priests who were anointed, whom Aaron consecrated and ordained to minister in the priest's office.
4 But 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. So Eleazar and Ithamar ministered in the priest's office in the presence and under the supervision of Aaron their father. [Lev. 10:1-4.]
5 And the Lord said to Moses,
6 Bring the tribe of Levi near and set them before Aaron the priest, that they may minister to him.
7 And they shall carry out his instructions and the duties connected with the whole assembly before the Tent of Meeting, doing the service of the tabernacle.
8 And they shall keep all the instruments and furnishings of the Tent of Meeting and take charge of [attending] the Israelites, to serve in the tabernacle.
