Numbers 3:2-4 GOD’S WORD Translation (GW)
2 The names of Aaron’s sons are Nadab (the firstborn), Abihu, Eleazar, and Ithamar. 3 These are the names of Aaron’s sons, the anointed priests, who were ordained to serve as priests. 4 Nadab and Abihu died in the Lord’s presence because they offered unauthorized fire in his presence in the Desert of Sinai. They had no children. So only Eleazar and Ithamar served as priests during the lifetime of their father Aaron.
