Numbers 3:2-4 Holman Christian Standard Bible (HCSB)
2 These are the names of Aaron’s sons: Nadab, the firstborn, and Abihu, Eleazar, and Ithamar. 3 These are the names of Aaron’s sons, the anointed priests, who were ordained to serve as priests. 4 But Nadab and Abihu died in the Lord’s presence when they presented unauthorized fire before the Lord in the Wilderness of Sinai, and they had no sons. So Eleazar and Ithamar served as priests under the direction of Aaron their father.
