1 Now these are the records of the generations of Aaron and Moses at the time when the LORD spoke with Moses on Mount Sinai. 2 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 anointed priests, whom he ordained to serve as priests. 4 But 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. So Eleazar and Ithamar served as priests in the lifetime of their father Aaron.
