Against the background of the rules that dominate Leviticus, the death of Aaron’s sons, Nadav and Abihu, makes a harrowing contrast. The seven-day priestly ordination ceremony has just been completed. The two young men now go to make an offering, and they are consumed by the sacrificial fire. Why? The text says it is because they offered “alien” or “strange” fire. We are supposed to accept this as the divine rationale, but I am hardly the first person to find this a thin explanation. In fact, I have come to believe that Moses got this one wrong. He seems especially obtuse when he berates Aaron and his remaining nephews for not eating that day’s sin offering. Perhaps there is no room for accidents in Moses' theology, but could he not just leave these deaths as something we don’t understand?
And Nadav, whose name meant “giving,” and Abihu,
“G-d, my father,” went to offer sprigs
of incense, the first fruits of their new work.
They wore their linen breeches; they washed their feet,
for they were rightly reverent. But fire,
as fire will, broke free from their pans,
lit the sashes—woven with such care
of purple, red, and blue—like wicks, and they,
like candles, burned. There is no why to this.
Say “alien fire,” and we’re already stumbling
in the mortal realm of commentary.
Then Moses inquired about the goat of sin offering, and it had already been burned! He was angry with Eleazar and Ithamar, Aaron's remaining sons, and said, "Why did you not eat the sin offering in the sacred area? For it is most holy, and He has given it to you to remove the guilt of the community and to make expiation for them before the Lord. Since its blood was not brought inside the sanctuary, you should certainly have eaten it in the sanctuary, as I commanded." And Aaron spoke to Moses, "See, this day they brought their sin offering and their burnt offering before the Lord, and such things have befallen me! Had I eaten sin offering today, would the Lord have approved?" And when Moses heard this, he approved. (Leviticus 10:17-19)
So many mitzvoth*—To know that G-d exists.
Not to add to the commandments of Torah.
Surely Aaron understood those now.
But what of the six hundred and eleven?
To set the showbread and the frankincense
before the Lord. To keep the fire burning
on the altar of the sacrifices.
To help the beast of burden if he stumbles
under his load. Not to defile yourself
by contact with the dead. Not to test
the word of G-d. Not to bear a grudge
or slay the innocent or take revenge.
And if the priest, having watched his sons
be dragged, by their singed tunics, outside the camp,
(and he, barred from rending his sacred vestments
or touching their dear, charred forms) should cry out,
should refuse to eat—even the sin
offering—what Lord would not approve?
* There are 613 mitzvoth or commandments in the Torah, dealing with everything from the treatment of the poor to marriage to various ritual practices. A number deal specifically with the duties of the priests.
