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

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

But Nadab and Abihu died before their father, and had no children: therefore Eleazar and Ithamar executed the priest's office.

David with Zadok of the sons of Eleazar, and Ahimelech of the sons of Ithamar, divided them according to their ordering in their service.

There were more chief men found of the sons of Eleazar than of the sons of Ithamar; and they were divided like this: of the sons of Eleazar there were sixteen, heads of ancestral houses; and of the sons of Ithamar, according to their fathers' houses, eight.

And thus were they divided impartially by drawing lots; for there were officiers of the sanctuary, and officiers of God, both of the sons of Eleazar, and of the sons of Ithamar.

And Shemaiah the son of Nethanel the scribe, who was of the Levites, wrote them in the presence of the king, and the officiers, and Zadok the priest, and Ahimelech the son of Abiathar, and the heads of the ancestral houses of the priests and of the Levites; one fathers' house being taken for Eleazar, and one taken for Ithamar.
