ABIHU å bī’ hū (אֲבִיה֔וּא, the [my] father is he). The second of the four sons of Aaron and Elisheba (Exod 6:23; Num 3:2; 26:60; 1 Chron 6:3; 24:1). When Moses ascended Mt. Sinai, Aaron, Nadab, and Abihu, with seventy elders, went part of the way up Sinai with him at the command of the Lord “and they saw the God of Israel” (Exod 24:1, 9, 10). Aaron and his sons, Nadab, Abihu, Eleazar, and Ithamar, were consecrated as priests according to the word of the Lord (Exod 28:1; Num 3:2, 3; 1 Chron 24:1). Abihu and his older brother Nadab were slain by the Lord when they offered “unholy fire before the Lord” which the Lord “had not commanded” (Lev 10:1, 2). Neither Nadab nor Abihu had any sons (Num 3:4; 1 Chron 24:2).
