1 This is how Aaron’s descendants, the priests, were divided into groups for service. The sons of Aaron were Nadab, Abihu, Eleazar, and Ithamar.
2 But Nadab and Abihu died before their father, and they had no sons. So only Eleazar and Ithamar were left to carry on as priests.
3 With the help of Zadok, who was a descendant of Eleazar, and of Ahimelech, who was a descendant of Ithamar, David divided Aaron’s descendants into groups according to their various duties.
4 Eleazar’s descendants were divided into sixteen groups and Ithamar’s into eight, for there were more family leaders among the descendants of Eleazar.
