1 Chronicles 24:2 In-Context

1 The divisions of Aaron's descendants were as follows: Aaron's sons were Nadab and Abihu, Eleazar and Ithamar.

2 Nadab and Abihu died before their father died, and neither had any children. So Eleazar and Ithamar served as priests.

3 David, Eleazar's descendant Zadok, and Ithamar's descendant Ahimelech divided Aaron's descendants into groups for service.

4 Since Eleazar's descendants had more men who were family heads than Ithamar's descendants, they were divided so that Eleazar's descendants had 16 family leaders and Ithamar's descendants had 8 family leaders.

5 Both groups were divided impartially by drawing lots so that there were officers for the holy place and officers for God among both Eleazar's and Ithamar's descendants.
