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

AC 3902. In the preceding chapter by the four sons of Jacob from Leah there was described the state of the church, or of the man who is becoming a church, as to the ascent from the truth which is of faith to the good which is of love. In this chapter, by Jacob’s sons from the maidservants of Rachel and Leah, and from Leah, and lastly from Rachel, there is described the conjunction of natural truth with spiritual good through means, and this in the order in which it is effected in the man who is being regenerated.

AC 3903. After this conjunction there is described the fructification and multiplication of truth and good, which is signified by the flock that Jacob procured for himself by means of the flock of Laban.
