³  And David distributeth them, and Zadok of the sons of Eleazar, and Ahimelech of the sons of Ithamar, according to their office in their service;

⁴  and there are found of the sons of Eleazar more for heads of the mighty men than of the sons of Ithamar; and they distribute them: Of the sons of Eleazar, heads for a house of fathers, sixteen; and of the sons of Ithamar, for a house of their fathers, eight.

⁵  And they distribute them, by lots, one with another, for princes of the sanctuary, and princes of God, have been of the sons of Eleazar, and of the sons of Ithamar.

⁶  And Shemaiah son of Nethaneel the scribe, of the Levites, writeth them before the king and the princes, and Zadok the priest, and Ahimelech son of Abiathar, and heads of the fathers, for priests and for Levites: one house of a father being taken possession of for Eleazar, and one being taken possession of for Ithamar.
