And these are the names of the sons of Aaron: Nadab the first-born, and Abihu, Eleazar, and Ithamar.

And Nadab and Abihu died before LORD when they offered strange fire before LORD in the wilderness of Sinai, and they had no sons. And Eleazar and Ithamar ministered in the priest's office in the presence of Aaron their father.

This is the service of the families of the sons of the Gershonites in the tent of meeting. And their charge shall be under the hand of Ithamar the son of Aaron the priest.

This is the service of the families of the sons of Merari, according to all their service, in the tent of meeting, under the hand of Ithamar the son of Aaron the priest.

And he gave four wagons and eight oxen to the sons of Merari, according to their service, under the hand of Ithamar the son of Aaron the priest.

And to Aaron were born Nadab and Abihu, Eleazar and Ithamar.
