In Context

2 The names of the sons of Aaron were Nadab the firstborn and Abihu, Eleazar and Ithamar.

3 Those were the names of Aaron's sons, the anointed priests, who were ordained to serve as priests.

4 Nadab and Abihu, however, fell dead before the Lord when they made an offering with unauthorized fire before him in the Desert of Sinai. They had no sons; so only Eleazar and Ithamar served as priests during the lifetime of their father Aaron.

5 The Lord said to Moses,

6 "Bring the tribe of Levi and present them to Aaron the priest to assist him.

7 They are to perform duties for him and for the whole community at the Tent of Meeting by doing the work of the tabernacle.
