1 The divisions of the Aaronites:Aaron’s family: Nadab, Abihu, Eleazar, and Ithamar.
2 Nadab and Abihu died before their father did, without having sons, and so Eleazar and Ithamar served as priests.
3 David, with the help of Zadok from Eleazar’s family and Ahimelech from Ithamar’s family, divided them according to their appointed duties.
4 Since Eleazar’s family was found to have more male heads than Ithamar’s family, they divided them so that Eleazar’s family had sixteen household heads and Ithamar’s family had eight.
