Numbers 3:1-4

YLT(i) 1 And these are births of Aaron and Moses, in the day of Jehovah's speaking with Moses in mount Sinai. 2 And these are the names of the sons of Aaron: the first-born Nadab, and Abihu, Eleazar, and Ithamar; 3 these are the names of the sons of Aaron, the anointed priests, whose hand he hath consecrated for acting as priest. 4 And Nadab dieth—Abihu also—before Jehovah, in their bringing near strange fire before Jehovah, in the wilderness of Sinai, and sons they had not; and Eleazar—Ithamar also—acteth as priest in the presence of Aaron their father.
