1 These are the family records of Aaron and Moses at the time the Lord spoke with Moses on Mount Sinai.
2 These are the names of Aaron’s sons: Nadab, the firstborn, and Abihu, Eleazar, and Ithamar.
3 These are the names of Aaron’s sons, the anointed priests, who were ordained to serve as priests.
4 But Nadab and Abihu died in the Lord’s presence when they presented unauthorized fire before the Lord in the Wilderness of Sinai, and they had no sons. So Eleazar and Ithamar served as priests under the direction of Aaron their father.
5 The Lord spoke to Moses:
6 “Bring the tribe of Levi near and present them to Aaron the priest to assist him.
7 They are to perform duties for him and the entire community before the tent of meeting by attending to the service of the tabernacle.
