1 Chronicles 24:1 In-Context

1 These are the groups to which the descendants of Aaron belong. Aaron had four sons: Nadab, Abihu, Eleazar, and Ithamar.

2 Nadab and Abihu died before their father did, and left no descendants, so their brothers Eleazar and Ithamar became priests.

3 King David organized the descendants of Aaron into groups according to their duties. He was assisted in this by Zadok, a descendant of Eleazar, and by Ahimelech, a descendant of Ithamar.

4 The descendants of Eleazar were organized into sixteen groups, while the descendants of Ithamar were organized into eight; this was done because there were more male heads of families among the descendants of Eleazar.

5 Since there were Temple officials and spiritual leaders among the descendants of both Eleazar and Ithamar, assignments were made by drawing lots.
