1 Chronicles 24:2 In-Context

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 priests.

3 With the help of Eleazar’s descendant Zadok and Ithamar’s descendant Ahimelech, David divided them according to the offices of their service.

4 Since more leaders were found among Eleazar’s descendants than those of Ithamar, they were divided accordingly. There were sixteen heads of families from the descendants of Eleazar and eight from the descendants of Ithamar.

5 Thus they were divided by lot, for there were officers of the sanctuary and officers of God among both Eleazar’s and Ithamar’s descendants.
