1 Now the divisions of the sons of Aaron were these.The sons of Aaron: Nadab, Abihu, Eleazar, and Ithamar.
2 But Nadab and Abihu died before their father, and they had no sons. So Eleazar and Ithamar served as priests.
3 Then David, along with Zadok of the sons of Eleazar and Ahimelek of the sons of Ithamar, divided them to their offices by their service.
4 Since the sons of Eleazar were found to have more chief men than the sons of Ithamar, they divided them into sixteen heads of the fathers’ houses for the sons of Eleazar, and eight for the sons of Ithamar, according to their fathers’ houses.
5 So they divided them by lots, the one as the other, for there were officers of the sanctuary and officers of God among both the sons of Eleazar and Ithamar.
