1 Chronicles 24:2-4

Lexham English Bible

² And Nadab and Abihu died before their father, and they had no sons,^[a] so Eleazar and Ithamar served as priests. ³ And David, with Zadok of the sons of Eleazar and Ahimelech of the sons of Ithamar, divided them according to their appointments for their service. ⁴ And more sons of Eleazar were found as heads of the men than the sons of Ithamar, so they divided them to the sons of Eleazar to be sixteen heads over the house of the fathers, and to the sons of Ithamar over the house of the fathers were eight heads.
