1. When the Lord talked with Moses on Mount Sinai,
2. Aaron's four sons, Nadab, Abihu, Eleazar, and Ithamar,
3. were the ones to be ordained as priests.
4. But the Lord killed Nadab and Abihu in the Sinai Desert when they used fire that was unacceptable in their offering to the Lord. And because Nadab and Abihu had no sons, only Eleazar and Ithamar served as priests with their father Aaron.
