Ithamar

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

“Next, have your brother Aaron brought to you from among the Israelites, along with his sons Nadab, Abihu, Eleazar, and Ithamar, to serve Me as priests.

This is the inventory for the tabernacle, the tabernacle of the Testimony, as recorded at Moses’ command by the Levites under the direction of Ithamar son of Aaron the priest.

Then Moses said to Aaron and his sons Eleazar and Ithamar, “Do not let your hair become disheveled and do not tear your garments, or else you will die, and the LORD will be angry with the whole congregation. But your brothers, the whole house of Israel, may mourn on account of the fire that the LORD has ignited.

And Moses said to Aaron and his remaining sons, Eleazar and Ithamar, “Take the grain offering that remains from the offerings made by fire to the LORD and eat it without leaven beside the altar, because it is most holy.

Later, Moses searched carefully for the goat of the sin offering, and behold, it had been burned up. He was angry with Eleazar and Ithamar, Aaron’s remaining sons, and asked,

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

Nadab and Abihu, however, died in the presence of the LORD when they offered unauthorized fire before the LORD in the Wilderness of Sinai. And since they had no sons, only Eleazar and Ithamar served as priests during the lifetime of their father Aaron.

This is the service of the Gershonite clans at the Tent of Meeting, and their duties shall be under the direction of Ithamar son of Aaron the priest.

This is the service of the Merarite clans according to all their work at the Tent of Meeting, under the direction of Ithamar son of Aaron the priest.”

and he gave the Merarites four carts and eight oxen, as their service required, all under the direction of Ithamar son of Aaron the priest.

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

The children of Amram: Aaron, Moses, and Miriam. The sons of Aaron: Nadab, Abihu, Eleazar, and Ithamar.

These were the divisions of the descendants of Aaron. The sons of Aaron were Nadab, Abihu, Eleazar, and Ithamar.

But Nadab and Abihu died before their father did, and they had no sons; so Eleazar and Ithamar served as priests.

With the help of Eleazar’s descendant Zadok and Ithamar’s descendant Ahimelech, David divided them according to the offices of their service.

Since more leaders were found among Eleazar’s descendants than those of Ithamar, they were divided accordingly. There were sixteen heads of families from the descendants of Eleazar and eight from the descendants of Ithamar.

Thus they were divided by lot, for there were officers of the sanctuary and officers of God among both Eleazar’s and Ithamar’s descendants.

The scribe, Shemaiah son of Nethanel, a Levite, recorded their names in the presence of the king and of the officers: Zadok the priest, Ahimelech son of Abiathar, and the heads of families of the priests and the Levites—one family being taken from Eleazar, and then one from Ithamar.
