1. There were also divisions for the sons of Aaron. The sons of Aaron were Nadab, Abihu, Eleazar, and Ithamar.
2. Nadab and Abihu died before their father, leaving no sons; therefore only Eleazar and Ithamar served as priests.
3. David, with Zadok, a descendant of Eleazar, and Ahimelech, a descendant of Ithamar, apportioned them their offices in the priestly service.
4. But since the sons of Eleazar were found to be more numerous by male heads than those of Ithamar, the former were divided into sixteen groups, and the latter into eight groups, each under its family heads.
