In Genesis 11, we met Abram for the first time, as his genealogy was traced down through the generations from Noah. Abram represents the beginning of a new spiritual state of humankind - a new church that would record preserve important external truths. Those external truths contained internal ones - true ideas about God the way people should live.
These external truths were encoded in stories, first preserved in oral traditions then in written scriptures in the time of Moses. In the current , Abram, goes, as commanded by God, the land of Canaan. In doing this, he effectively starts the Hebrew church (from Eber, Abraham's forebear).
All the geographic places in the land of Canaan its environs had been given spiritual significations by the people of the Most Ancient Church. In the new Word that would be written there, these places would be mentioned by name would signify spiritual ideas.
When Abraham is driven by famine in the land seek refuge in Egypt, it symbolizes a state of initial instruction for this new church. That early instruction is of an external type. Egypt, in the Word, represents scientific knowledge - the natural sciences - which teach the natural level in people.
There are two levels of "story" nested in the symbolism of the literal text. One is the spiritual story of humankind. Another, higher one, is the story of the inner spiritual process that would take place in the life of Jesus Christ. Both stories are traced out in Swedenborg's exegesis of the Word.
Here's an excerpt from his capstone work, True Christian Religion:
The Word has two senses hidden in its literal sense; these are called the spiritual the celestial senses. In the spiritual sense the contents of the Word refer chiefly the church in the celestial sense chiefly the Lord. Again in the spiritual sense its contents refer Divine truth in the celestial sense Divine good. (True Christian Religion 248)
