1 Chronicles 24:2 In-Context

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

2 But Nadab and Abihu died before their father, and they had no sons, so Eleazar and Ithamar served as priests.

3 Together with Zadok from the sons of Eleazar and Ahimelech from the sons of Ithamar, David divided them according to the assigned duties of their service.

4 Since more leaders were found among Eleazar's descendants than Ithamar's, they were divided [accordingly]: 16 heads of ancestral houses were from Eleazar's descendants, and eight [heads] of ancestral houses were from Ithamar's.

5 They were divided impartially by lot, for there were officers of the sanctuary and officers of God among both Eleazar's and Ithamar's descendants.
