Numbers 3:2 ASV

¹  Now these are the generations of Aaron and Moses in the day that Jehovah spake with Moses in mount Sinai.

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 that were anointed, whom he consecrated to minister in the priest's office.

⁴  And Nadab and Abihu died before Jehovah, when they offered strange fire before Jehovah, in the wilderness of Sinai, and they had no children; and Eleazar and Ithamar ministered in the priest's office in the presence of Aaron their father.
