1 Chronicles 24:2-4

International Standard Version

² But Nadab and Abihu died before their father did, leaving no sons, so Eleazar and Ithamar became priests. ³ Along with Zadok, one of Eleazar’s descendants, and Ahimelech, one of Ithamar’s descendants, David organized their service according to their assigned responsibilities.

⁴ More leaders were located among Eleazar’s descendants than among those of Ithamar, so sixteen leaders were appointed from the leaders of the ancestral households of Eleazar’s descendants and eight from those of Ithamar.
