1 Chronicles 24:1-2

New International Version

The Divisions of Priests

24 These were the divisions^(A) of the descendants of Aaron:^(B)

The sons of Aaron were Nadab, Abihu, Eleazar and Ithamar.^{(C) 2} But Nadab and Abihu died before their father did,^(D) and they had no sons; so Eleazar and Ithamar served as the priests.
