One priest, Zadok, from Eleazar's descendants and another priest, Ahimelech, from Ithamar's descendants were designated to help create the various priestly orders. Sixteen of Eleazar's descendants were selected to head priestly orders while only eight of Ithamar's descendants were so chosen.
Two priests, Zadok from Eleazar's line and Ahimelech from Ithamar's line, were appointed to organize different priestly groups. Sixteen members from Eleazar's lineage were chosen as leaders for the priestly orders, whereas only eight from Ithamar's lineage received this role.
