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

And Nadab and Abihu died before Jehovah when they offered strange fire before Jehovah in the wilderness of Sinai, and they had no sons; and Eleazar and Ithamar exercised the priesthood in the presence of Aaron their father.

This is the service of the families of the sons of Gershon 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 four waggons and eight oxen he gave 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.
