Numbers 3:2-4

Webster(i) 2 And these are the names of the sons of Aaron; Nadab the first-born, and Abihu, Eleazar, and Ithamar. 3 These are the names of the sons of Aaron, the priests who were anointed, whom he consecrated to minister in the priest's office. 4 And Nadab and Abihu died before the LORD, when they offered strange fire before the LORD, in the wilderness of Sinai, and they had no children: and Eleazar and Ithamar ministered in the priest's office in the sight of Aaron their father.
