1 Chronicles 24:2-4

Amplified Bible, Classic Edition

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.

⁴ Since there were more chief men found among the sons of Eleazar [because of the misfortunes of Eli, and Saul’s slaughter of the priests at Nob] than among the sons of Ithamar, they were divided thus: sixteen heads of fathers’ houses of the sons of Eleazar and eight of the sons of Ithamar according to their fathers’ houses.
