Numbers 3:2-4 Common English Bible (CEB)
2 These are the names of Aaron’s sons: Nadab the oldest, and Abihu, Eleazar, and Ithamar. 3 These are the names of Aaron’s sons, who are the anointed priests and ordained to the priesthood. 4 Nadab and Abihu died before the Lord when they made an unauthorized offering to the Lord in the Sinai desert. They didn’t have any sons. Eleazar and Ithamar served as priests during the lifetime of their father Aaron.
