1. These were the divisions of the descendants of Aaron:The sons of Aaron were Nadab, Abihu, Eleazar and Ithamar.
2. But Nadab and Abihu died before their father did, and they had no sons; so Eleazar and Ithamar served as the priests.
3. With the help of Zadok a descendant of Eleazar and Ahimelek a descendant of Ithamar, David separated them into divisions for their appointed order of ministering.
4. A larger number of leaders were found among Eleazar’s descendants than among Ithamar’s, and they were divided accordingly: sixteen heads of families from Eleazar’s descendants and eight heads of families from Ithamar’s descendants.
