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 took Elisheba, daughter of Amminadab and sister of Nahshon, as wife; she bore him Nadab, Abihu, Eleazar, and Ithamar.
God said to Moses, Come up to the Lord, you and Aaron, Nadab and Abihu [Aaron's sons], and seventy of Israel's elders, and worship at a distance.
Then Moses, Aaron, Nadab, and Abihu, and seventy of the elders of Israel went up [the mountainside].
From among the Israelites take your brother Aaron and his sons with him, that he may minister to Me in the priest's office, even Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.
And Nadab and Abihu, the sons of Aaron, each took his censer and put fire in it, and put incense on it, and offered strange and unholy fire before the Lord, as He had not commanded them. And there came forth fire from before the Lord and killed them, and they died before the Lord.
These are the names of the sons of Aaron: Nadab the firstborn, 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 ministered in the priest's office in the presence and under the supervision of Aaron their father.
