1 Chronicles 24:2 In-Context

1 And the courses of the sons of Aaron [were these]. The sons of Aaron: Nadab and Abihu, Eleazar and Ithamar.

2 But Nadab and Abihu died before their father, and had no children: therefore Eleazar and Ithamar executed the priest's office.

3 And David with Zadok of the sons of Eleazar, and Ahimelech of the sons of Ithamar, divided them according to their ordering in their service.

4 And there were more chief 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 of the sons of Ithamar, according to their fathers' houses, eight.

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