As this story begins, the Children of Israel have escaped Egypt, and are camped near Mount Sinai. Moses, their leader, as climbed up the mountain, and is receiving the Ten Commandments from Jehovah. The people get impatient, and think that perhaps Moses will not return, and they ask his brother Aaron, the High Priest, to make them new gods.

Aaron complies - which is surprising - given that he has been involved in the Exodus since the beginning, supporting Moses. But he does, and collects golden earrings, melts them down , and fashions them into a golden idol shaped like a calf. He builds an altar before the calf, and proclaims a feast to Jehovah.

God sees what is happening, and is angry, telling Moses that he will destroy these people, and start over again, using Moses to start a new church. Moses persuades God not to do this, reminding him of the faith of Abraham, Isaac, and Jacob. Yet, as Moses descends from the mountain, carrying the Ten Commandments etched by the hand of God on two tables of stone, and sees the extent of the forbidden idolatry, he too is angry. He shatters the tables of stone, grinds the calf into dust, mixes the dust into water, and makes the people drink it.

What's the inner meaning of this story?

It's explained in detail in Arcana Coelestia, starting in section 10395. Every detail is important. Very briefly, though:

If we don't realize, or recognize, that the Word contains truths from God, we can react by "gathering to Aaron" - just being religiously observant in an external, perfunctory way.

Detached from internal worship, we gravitate to developing false ideas - idols - that we use in religious teachings and worship. Not knowing Moses's whereabouts means a total unawareness of the internal truths of the Word.

When Aaron gathers the earrings, that signifies the external church cherry-picking truths from the literal sense of the Word to support a man-made religion that reinforces what it loves.

We can think ways that churches that have done this, and on a personal level, there's a strong tendency for us to do this, too - to think shallowly, to extract things from the Word and mold them into idols, or justifications for the things we want to do.

The two tables of stone are inscribed on both sides. There are internals and externals of religion. We need both. This is the reason why the internal meaning of the Word is so important to us all; it contains the inner truths that we need to understand, and live by, and learn to love.

This is much too brief a summary to do the story justice; it's one of they key turning points in the religious history of humankind, and it has profound meaning for us as individuals, and for our churches and nations.

At the inmost level, the story of Moses -- like all of the Bible -- is about the Lord and his spiritual development during his human life as Jesus. Moses's role represents establishing forms of worship and to make the people obedient. As such, his primary representation is "the Law of God," the rules God gave the people of Israel to follow in order to represent spiritual things. This can be interpreted narrowly as the Ten Commandments, more broadly as the books of Moses, or most broadly as the entire Bible. Fittingly, his spiritual meaning is complex and important, and evolves throughout the course of his life. To understand it, it helps to understand the meaning of the events in which he was involved. At a more basic level, Moses's story deals with the establishment of the third church to serve as a container of knowledge of the Lord. The first such church -- the Most Ancient Church, represented by Adam and centered on love of the Lord -- had fallen prey to human pride and was destroyed. The second -- the Ancient Church, represented by Noah and the generations that followed him -- was centered on love of the neighbor, wisdom from the Lord and knowledge of the correspondences between natural and spiritual things. It fell prey to the pride of intelligence, however -- represented by the Tower of Babel -- and at the time of Moses was in scattered pockets that were sliding into idolatry. On an external level, of course, Moses led the people of Israel out of Egypt through 40 years in the wilderness to the border of the homeland God had promised them. Along the way, he established and codified their religious system, and oversaw the creation of its most holy objects. Those rules and the forms of worship they created were given as containers for deeper ideas about the Lord, deeper truth, and at some points -- especially when he was first leading his people away from Egypt, a time before the rules had been written down -- Moses takes on the deeper representation of Divine Truth itself, truth from the Lord. At other times -- especially after Mount Sinai -- he has a less exalted meaning, representing the people of Israel themselves due to his position as their leader. Through Moses the Lord established a third church, one more external than its predecessors but one that could preserve knowledge of the Lord and could, through worship that represented spiritual things, make it possible for the Bible to be written and passed to future generations.
