Numbers 3:1-4

Leeser(i) 1 And these are the generations of Aaron and Moses, on the day that the Lord spoke with Moses on mount Sinai. 2 And these are the names of the sons of Aaron: the firstborn Nadab, and Abihu, Elazar, and Ithamar. 3 These are the names of the sons of Aaron, the priests that were anointed, who were consecrated to minister as priests. 4 And Nadab and Abihu died before the Lord, when they offered a strange fire before the Lord, in the wilderness of Sinai, and they had no children: and Elazar and Ithamar ministered as priests in the life-time of Aaron their father.
