1 Chronicles 24:1-6

1. Now [these are] the divisions of the sons of Aaron. The sons of Aaron; Nadab, and Abihu, Eleazar, and Ithamar. 2. But Nadab and Abihu died before their father, and had no children: therefore Eleazar and Ithamar executed the priest’s office. 3. And David distributed them, both Zadok of the sons of Eleazar, and Ahimelech of the sons of Ithamar, according to their offices in their service. 4. And there were more chief men found of the sons of Eleazar than of the sons of Ithamar; and [thus] were they divided. Among the sons of Eleazar [there were] sixteen chief men of the house of [their] fathers, and eight among the sons of Ithamar according to the house of their fathers. 5. Thus were they divided by lot, one sort with another; for the governors of the sanctuary, and governors [of the house] of God, were of the sons of Eleazar, and of the sons of Ithamar. 6. And Shemaiah the son of Nethaneel the scribe, [one] of the Levites, wrote them before the king, and the princes, and Zadok the priest, and Ahimelech the son of Abiathar, and [before] the chief of the fathers of the priests and Levites: one principal household being taken for Eleazar, and [one] taken for Ithamar.
