Here are some excerpts from Swedenborg's "Arcana Coelestia" that help explain the inner meaning of this chapter:

AC 5396a. In the latter part of the last chapter the subject treated of was the influx and conjunction of the celestial of the spiritual with the memory-knowledges in the natural; and now the subject treated of is the influx and conjunction of the celestial of the spiritual with the truths of faith therein which are of the church.

AC 5397. First is described the endeavor to appropriate these truths by means of the memory-knowledges of the church, which are "Egypt," and without the intermediate, which is "Benjamin," together with truth from the Divine, which is "Joseph;" but in vain, wherefore they were sent back and come good of natural truth was given freely.
