Numbers 3:2-4

New American Standard Bible

^2 (A)These then are the names of the sons of Aaron: Nadab the firstborn, and Abihu, Eleazar and Ithamar. ³ These are the names of the sons of Aaron, the ^(B)anointed priests, whom he ^[a]ordained to serve as priests. ^4 (C)But Nadab and Abihu died in the presence of the Lord when they offered ^[b]strange fire before the Lord in the wilderness of Sinai; and they had no children. So Eleazar and Ithamar served as priests ^[c]in the lifetime of their father Aaron.
