[3:1] This is the family of Aaron and Moses at the time the Lord spoke to Moses on Mount Sinai.
[3:2] Aaron had four sons: Nadab, the oldest, Abihu, Eleazar, and Ithamar.
[3:3] They were anointed and ordained as priests,
[3:4] but Nadab and Abihu were killed when they offered unholy fire to the Lord in the Sinai Desert. They had no children, so Eleazar and Ithamar served as priests during Aaron's lifetime.
