1 Chronicles 24:4-5

4And 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.

5And they were divided by lot, one with another; for the princes of the sanctuary and the princes of 1God were of the sons of Eleazar and of the sons of Ithamar.
