1 Chronicles 24:3-6

Leeser(i) 3 And David divided them off with Zadok of the sons of El’azar’, and Achimelech of the sons of Ithamar, to their office in their service. 4 And the sons of El’azar were found more numerous in the chiefs of males than the sons of Ithamar; and they divided them accordingly. Of the sons of El’azar there were sixteen chiefs of the family divisions, and of the sons of Ithamar, eight for their family divisions. 5 And they divided them off by lot, both the first and the last; for the governors of the sanctuary, and governors of the house of God, were from the sons of El’azar, and from the sons of Ithamar. 6 And Shema’yah the son of Nethanel the scribe, one of the Levites, wrote them down before the king, and the princes, and Zadok the priest, and Achimelech the son of Ebyathar, and the chiefs of the families of the priests and Levites: one family division being drawn of El’azar, and one being equally drawn of Ithamar.
