1 Chronicles 24:2-4

Tree of Life Version

² But Nadab and Abihu died before their father and had no children, so Eleazar and Ithamar served as kohanim. ³ David, with Zadok of the sons of Eleazar and Ahimelech of the sons of Ithamar, divided them into their offices according to their avodah. ⁴ More leading men were found among the sons of Eleazar than among the sons of Ithamar, so they divided them: the sons of Eleazar had 16 leaders of clans and the sons of Ithamar had eight leaders of clans.
