Into the classes or courses following:

the sons of Aaron; Nadab and Abihu, Eleazar and Ithamar;

1 Chronicles 24:1 In-Context

1 The family of Aaron was grouped as follows: Aaron's sons were Nadab, Abihu, Eleazar, and Ithamar.

2 Nadab and Abihu died before their father and left no sons. So Eleazar and Ithamar filled the office of priest.

3 David assigned Zadok from the family of Eleazar and Ahimelech from the family of Ithamar and assigned them to separate divisions for carrying out their appointed ministries.

4 It turned out that there were more leaders in Eleazar's family than in Ithamar's and so they divided them proportionately: sixteen clan leaders from Eleazar's family and eight clan leaders from Ithamar's family.

5 They assigned the leaders by lot, treating both families alike, for there were officials of the sanctuary and officials of God among both the Eleazar and Ithamar families.
