1 Chronicles 24:3-5

New King James Version

³ Then David with Zadok of the sons of Eleazar, and ^(A)Ahimelech of the sons of Ithamar, divided them according to the schedule of their service.

⁴ There were more leaders found of the sons of Eleazar than of the sons of Ithamar, and thus they were divided. Among the sons of Eleazar were sixteen heads of their fathers’ houses, and eight heads of their fathers’ houses among the sons of Ithamar. ⁵ Thus they were divided by lot, one group as another, for there were officials of the sanctuary and officials of the house of God, from the sons of Eleazar and from the sons of Ithamar.
