Numbers 3:2-4

New International Reader's Version

² Aaron’s oldest son was Nadab. Aaron’s other sons were Abihu, Eleazar and Ithamar. ³ Those were the names of Aaron’s sons. They were the anointed priests. They were given authority to serve the Lord as priests. ⁴ But Nadab and Abihu made an offering to the Lord by using fire that wasn’t allowed. So they died in front of him. That happened in the Desert of Sinai. They didn’t have any sons. Only Eleazar and Ithamar served as priests while their father Aaron was living.
