Aaron married Elisheba, the daughter of Amminadab, the sister of Nahshon, and she bore him Nadab and Abihu, Eleazar and Ithamar.

“Then bring near to yourself Aaron your brother, and his sons with him, from among the sons of Israel, to minister as priest to Me—Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron’s sons.

This is the number of the things for the tabernacle, the tabernacle of the testimony, as they were numbered according to the command of Moses, for the service of the Levites, by the hand of Ithamar the son of Aaron the priest.

Then Moses said to Aaron and to his sons Eleazar and Ithamar, “Do not uncover your heads nor tear your clothes, so that you will not die and that He will not become wrathful against all the congregation. But your kinsmen, the whole house of Israel, shall bewail the burning which the Lord has brought about.

Then Moses spoke to Aaron, and to his surviving sons, Eleazar and Ithamar, “Take the grain offering that is left over from the Lord’s offerings by fire and eat it unleavened beside the altar, for it is most holy.

But Moses searched carefully for the goat of the sin offering, and behold, it had been burned up! So he was angry with Aaron’s surviving sons Eleazar and Ithamar, saying,

These then are the names of the sons of Aaron: Nadab the firstborn, and Abihu, Eleazar and Ithamar.

Now the divisions of the descendants of Aaron were these: the sons of Aaron were Nadab, Abihu, Eleazar and Ithamar.

But Nadab and Abihu died before their father and had no sons. So Eleazar and Ithamar served as priests.

David, with Zadok of the sons of Eleazar and Ahimelech of the sons of Ithamar, divided them according to their offices for their ministry.

Since more chief men were found from the descendants of Eleazar than the descendants of Ithamar, they divided them thus: there were sixteen heads of fathers’ households of the descendants of Eleazar and eight of the descendants of Ithamar, according to their fathers’ households.

Thus they were divided by lot, the one as the other; for they were officers of the sanctuary and officers of God, both from the descendants of Eleazar and the descendants of Ithamar.

Shemaiah, the son of Nethanel the scribe, from the Levites, recorded them in the presence of the king, the princes, Zadok the priest, Ahimelech the son of Abiathar, and the heads of the fathers’ households of the priests and of the Levites; one father’s household taken for Eleazar and one taken for Ithamar.
