Abihu
Abihu is the second son of Aaron the priest, born to Aaron and Elisheba. With his older brother Nadab and his younger brothers Eleazar and Ithamar, he is named to the Aaronic priesthood at its founding. He is admitted to the inner circle that ascends Sinai to see Yahweh, and then, almost immediately after his consecration, he is consumed by fire from Yahweh for offering unauthorized incense. He leaves no descendants.
Birth and Family
Abihu's parentage is given in the genealogy of Levi. "Aaron took to himself Elisheba, the daughter of Amminadab, the sister of Nahshon, as wife; and she bore him Nadab and Abihu, Eleazar and Ithamar" (Ex 6:23). The roster is repeated when the Levitical census is taken in the wilderness, and there Nadab is fixed as the eldest: "these are the names of the sons of Aaron: Nadab the firstborn, and Abihu, Eleazar, and Ithamar" (Nu 3:2). Abihu is therefore second in the line, paired throughout the narrative with his older brother.
Summoned to Sinai
Before the priesthood is formalized, Abihu is included in the small company called up the holy mountain. Yahweh tells Moses, "Come up to Yahweh, you, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel; and you⁺ worship far off" (Ex 24:1). The summons is carried out: "Then went up Moses, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel" (Ex 24:9). Abihu is thus among the very few permitted to approach Yahweh on Sinai, prior to any consecration as priest.
Called to the Priesthood
When Yahweh institutes the priesthood, Abihu is named in the founding charter: "you bring near to you Aaron your brother, and his sons with him, from among the sons of Israel, that he may serve me in the priest's office, even Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons" (Ex 28:1). The call places Abihu in the inaugural generation of priests alongside his father and brothers.
Strange Fire and Death
The narrative turns on a single act of unauthorized worship. "Nadab and Abihu, the sons of Aaron, each of them took his censer, and put fire in it, and laid incense on it, and offered strange fire before Yahweh, which he had not commanded them" (Le 10:1). The judgment is immediate: "And there came forth fire from before Yahweh, and devoured them, and they died before Yahweh" (Le 10:2). The cause given by the text itself is the unauthorized character of the offering — fire "which he had not commanded them."
The Numbers narrative restates the same verdict twice, fixing it in the wilderness chronology and pairing it with the priestly succession. "Nadab and Abihu died before Yahweh, when they offered strange fire before Yahweh, in the wilderness of Sinai, and they had no sons; and Eleazar and Ithamar served in the priest's office in the presence of Aaron their father" (Nu 3:4). And again in the second census: "Nadab and Abihu died, when they offered strange fire before Yahweh" (Nu 26:61).
Childlessness and Succession
Abihu's death is total in genealogical as well as personal terms. Nu 3:4 records that he and Nadab "had no sons," and the same verse names Eleazar and Ithamar as the priestly line that continues. Abihu's name therefore appears in the founding lists of Aaron's house but disappears from the subsequent priestly genealogy.
