Second son of Aaron (Ex 6:23; Nu 3:2; 26:60; 1Ch 6:3; 24:1); accompanied Moses to the top of Sinai (Ex 24:1,9); admitted to the priest's office (Ex 28:1); slain along with his brother Nadab for offering strange fire (Le 10:1-2; Nu 3:4; 26:61; 1Ch 24:2).
Aaron married Elisheba, the daughter of Amminadab, the sister of Nahshon, and she bore him Nadab and Abihu, Eleazar and Ithamar.
Then He said to Moses, "Come up to the LORD, you and Aaron, Nadab and Abihu and seventy of the elders of Israel, and you shall worship at a distance.
Then Moses went up with Aaron, Nadab and Abihu, and seventy of the elders of Israel,
"Then bring near to yourself Aaron your brother, and his sons with him, from among the sons of Israel, to minister as priest to Me--Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.
Now Nadab and Abihu, the sons of Aaron, took their respective firepans, and after putting fire in them, placed incense on it and offered strange fire before the LORD, which He had not commanded them. And fire came out from the presence of the LORD and consumed them, and they died before the LORD.
These then are the names of the sons of Aaron: Nadab the firstborn, and Abihu, Eleazar and Ithamar.
But Nadab and Abihu died before the LORD when they offered strange fire before the LORD in the wilderness of Sinai; and they had no children. So Eleazar and Ithamar served as priests in the lifetime of their father Aaron.
