There seems to have been an ancient work, long since lost, documenting conquest of Canaan. It is in a way parallel to the story of the patriarchs (partially recorded in Genesis) and the establishment of the Kingdom (in Samuel). In the scriptures we now have, it seems primarily scattered in Exodus (covering the baptism of blood and the construction of the Tabernacle), Numbers (called The Wilderness in Hebrew), and Joshua (the action-climax and post-action denouement of the story).

It’s also the story of Moses’s moral decay: that "most humble man" is the Walter White of the Bible. But just as Breaking Bad is the story not just of Walter’s decay but of the grief of those around him, these scriptures are the story not just of Moses’s decline but the story of the deaths of those he loved.

To see this, look at the book immediately before Numbers: Leviticus. It is primary a book of laws, a journal of the well ordered place of fetishism in human society. But there’s one chapter of narrative in Leviticus that’s required to understand Numbers — the death of Aaron’s sons:

Then Nadab and Abihu, the sons of Aaron, each took his censer and put fire in it, put incense on it, and offered profane fire before the LORD, which He had not commanded them.

So fire went out from the LORD
and devoured them,
and they died before the LORD.

And Moses said to Aaron, "This is what the LORD spoke, saying:

‘By those who come near Me
I must be regarded as holy;
And before all the people
I must be glorified.’"

So Aaron held his peace.
Leviticus 10:1-3

The baptism of blood in Exodus may symbolize the loss of the part to save the whole. But Leviticus-Numbers feels like just loss. Aaron loses his sons. Moses loses his brother Aaron.

Moses stripped Aaron of his garments and put them on Eleazar his son;
and Aaron died there on the top of the mountain.

Then Moses and Eleazar came down from the mountain. Now when all the congregation saw that Aaron was dead, all the house of Israel mourned for Aaron thirty days.
Numbers 20:28-29

Moses loses his divine authority.

Then the LORD spoke to Moses and Aaron,

"Because you did not believe Me,
to hallow Me in the eyes of the children of Israel,
therefore you shall not bring this assembly
into the land which I have given them."
Numbers 20:12

And then even his humanity.

And Moses said to them: "Have you kept all the women alive? Look, these women caused the children of Israel, through the counsel of Balaam, to trespass against the LORD in the incident of Peor, and there was a plague among the congregation of the LORD. Now therefore, kill every male among the little ones, and kill every woman who has known a man intimately.
Numbers 31:15-17

The same theme of loss is reflected in the adversaries of the Israelites, the Canaanite kings who fear the loss of their lands, and the wizard Balaam who prophesied the victory of Almighty God:

They killed the kings of Midian with the rest of those who were killed—Evi, Rekem, Zur, Hur, and Reba, the five kings of Midian.

Balaam the son of Beor they also killed with the sword.
Numbers 31:8

And even the people themselves:

For the LORD had said of them,

"They shall surely die in the wilderness."

So there was not left a man of them, except Caleb the son of Jephunneh and Joshua the son of Nun.
Numbers 26:65

Through Leviticus-Numbers Aaron the High Priest lost his family, his life, and even (though the horrific actions of Moses) his legacy through his brother. Battles will be won in the future, after the end of his natural life, but for the wilderness generation there is pain, and murmuring, and death, and loss.

What should be made of this?

The High Priest loses everything, including his life, including the lives of his people. He is betrayed by those entrusted to help him. He loses those closest to him.

These themes are documented elsewhere in the Bible. That sense of successful futility in Ecclesiastes and Job, the slow political destruction of Kings, the horror of Lamentations or the post-Resurrection despair felt by John. Are these all types of Lent, best understood as reflections of the time between Good Friday and Easter Sunday?

If we are to imitate Christ who harrowed hell on that day, what does that mean for us?

I don’t know. But whenever I feel pain I have experienced intellectualized like this, I feel like Aaron: hurt, sarcastic, questioning:

And Aaron said to Moses, "Look, this day they have offered their sin offering and their burnt offering before the LORD, and such things have befallen me!

If I had eaten the sin offering today, would it have been accepted in the sight of the LORD?"
Leviticus 10:19

What else are you expecting me to do?

What else, when even holding our peace is too much to bare?

I read the books of Leviticus and Numbers in Robert Alter’s translation.
