Numbers 3:2-4

New Life Version

² The names of the sons of Aaron are Nadab the first-born, Abihu, Eleazar and Ithamar. ³ These are the names of the sons of Aaron, the chosen religious leaders. Aaron set them apart to work as religious leaders. ⁴ But Nadab and Abihu died before the Lord when they made a fire that was not holy to the Lord in the Desert of Sinai. And they had no children. So Eleazar and Ithamar worked as religious leaders during the life-time of their father Aaron.
