Here is an excerpt from Swedenborg's "Arcana Coelestia" that helps explain the inner meaning of this chapter:

AC 5574. The subject is continued of the conjunction in the natural of the truths of the church, which are the "ten sons of Jacob," with the celestial of the spiritual, or truth from the Divine, which is "Joseph," through the intermediate which is "Benjamin;" but in this chapter, in the internal sense, only the general influx which precedes conjunction is treated of.
