1 Chronicles 24:3-5

Darby Translation

³ And David distributed them, both Zadok of the sons of Eleazar, and Ahimelech of the sons of Ithamar, according to their office in their service.

⁴ And there were more head-men found of the sons of Eleazar than of the sons of Ithamar, and [thus] were they divided: of the sons of Eleazar there were sixteen heads of fathers' houses, and eight of the sons of Ithamar according to their fathers' houses.

⁵ And they were divided by lot, one with another; for the princes of the sanctuary and the princes of God were of the sons of Eleazar and of the sons of Ithamar.
