Numbers 3:2-4

Douay-Rheims 1899 American Edition

² And these the names of the sons of Aaron: his firstborn Nadab, then Abiu, and Eleazar, and Ithamar.

³ These the names of the sons of Aaron the priests that were anointed, and whose hands were filled and consecrated, to do the functions of priesthood.

⁴ Now Nadab and Abiu died, without children, when they offered strange fire before the Lord, in the desert of Sinai: and Eleazar and Ithamar performed the priestly office in the presence of Aaron their father.
