Abihu, Son of Aaron: A Name in the Lists and a Fire That Ended Him
A priest of the tribe of Levi, in Egypt and the wilderness
Abihu (אֲבִיהוּא) belongs to the era of Egypt and the wilderness, placed at around 1706 BC to 1451 BC on Ussher's chronology (1650). He was of the tribe of Levi, a son of Aaron, and a priest. His whole footprint in Scripture is twelve verses across eight passages in four books: Exodus, Leviticus, Numbers and 1 Chronicles. He first appears at Exodus 6:23 and is last named in 1 Chronicles. That is the entire record. Anyone who comes looking for the story of Abihu will find instead a name that keeps turning up in lists, and one line of narrative about how he died.
Born into the family of Aaron
His birth is reported in a genealogy: "Aaron took Elisheba, the daughter of Amminadab, the sister of Nahshon, as his wife; and she bore him Nadab and Abihu, Eleazar and Ithamar" (Exodus 6:23). Four brothers, and Abihu is second. The same four names are repeated in 1 Chronicles 6:3: "The children of Amram: Aaron, Moses, and Miriam. The sons of Aaron: Nadab, Abihu, Eleazar, and Ithamar." The list appears again at Numbers 3:2, and again at the head of the priestly divisions in 1 Chronicles 24:1: "These were the divisions of the sons of Aaron. The sons of Aaron: Nadab, Abihu, Eleazar, and Ithamar."
It is worth noticing what the repetition means. Abihu's name was worth writing down four separate times, generations apart, by writers who had every reason to leave him out. He is not a footnote in the priestly record. He stands second in it.
Called up the mountain
The one place where Abihu moves rather than merely appears is Exodus 24. The summons comes: "He said to Moses, 'Come up to Yahweh, you, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel; and worship from a distance'" (Exodus 24:1). And the ascent follows: "Then Moses, Aaron, Nadab, Abihu, and seventy of the elders of Israel went up" (Exodus 24:9).
Abihu is named individually, before the seventy elders, in a company of the very few called toward Yahweh. He obeyed the summons. He went up. Whatever else is true of him, this is true: he was among those given access that Israel as a whole was not given.
His appointment to the priesthood is recorded at Exodus 28:1, alongside his father and brothers. The dossier carries that reference without its text, so it is left as it stands: a call to serve.
The strange fire
The end is stated with no softening: "To Aaron were born Nadab and Abihu, Eleazar and Ithamar. Nadab and Abihu died when they offered strange fire before Yahweh" (Numbers 26:60-61). The same event is recorded at Leviticus 10:1 and at Numbers 3:4.
The man who had been called up the mountain, and who had been set apart to the priesthood, brought before Yahweh what Yahweh had not asked for, and he died for it. Scripture puts the cause and the consequence in one sentence and does not explain further. It also does not excuse him. His nearness to God did not protect him from his own offering; if anything it is precisely because he stood so close that the wrongness of the fire mattered so much.
The cost is counted again in 1 Chronicles 24:2, in the ledger of the priesthood: "But Nadab and Abihu died before their father, and had no children: therefore Eleazar and Ithamar executed the priest's office." Two sentences carry three losses. He died before Aaron, so his father buried him. He had no children, so nothing of him continued. And the priestly office passed sideways to his younger brothers, Eleazar and Ithamar, who did the work Abihu had been ordained to do.
What we do not know
A great deal. No children are named for Abihu, and 1 Chronicles 24:2 says plainly there were none. No wife is named. No age is given, no words of his are recorded, and no scene is told about him in which he speaks or acts alone. Every mention is a list, a genealogy or a passing note, apart from the summons and ascent of Exodus 24:1 and 24:9. What he intended by the strange fire, what he was thinking, whether he had been warned, the text does not say, and neither will we.
A name that stayed
What remains of Abihu is his name in the record of Aaron's sons, held there by Exodus 6:23, 1 Chronicles 6:3, Numbers 3:2, Numbers 26:60 and 1 Chronicles 24:1, and beside it the reason he is no longer in the priesthood. Israel kept both halves. The privilege of Exodus 24:9 and the fire of Numbers 26:61 belong to the same man, and Scripture refuses to let us have one without the other.
