1 Chronicles 24:1-3

Amplified Bible, Classic Edition

24 The courses or divisions of the priests, the sons of Aaron, were these: The sons of Aaron: Nadab, and Abihu, Eleazar, and Ithamar.

² But Nadab and Abihu died before their father and had no children; therefore Eleazar and Ithamar executed the priest’s office.

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