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

AC 3656. In the supreme sense this chapter treats of the Lord, how He began to make His natural Divine both as to truth and as to good; and the means by which He effected this are described in general. But in the representative sense it treats of how the Lord regenerates or makes new the natural of man both as to truth and as to good; the process in general is in like manner described (verses 1 to 10).

AC 3657. In the internal supreme sense there is described how the Lord began to make His natural Divine as to truth from the ultimate of order, that thereby He might make disposition of the intermediates, and might conjoin each and all things with the First; that is, with His Divine Itself. But in the internal representative sense there is described how the Lord regenerates the human natural also from the ultimate of order, and thereby disposes the intermediates, in order that through the rational He may conjoin them with Himself (verses 11 to 22).

3658. THE INTERNAL SENSE

Verses 1-2 And Isaac called to Jacob, and blessed him, and commanded him, and said to him, You shall not take a wife from the daughters of Canaan. Rise up, go to Paddan Aram, to the home of Bethuel your mother's father, and take for yourself from there a wife from the daughters of Laban your mother's brother.

'Isaac called to Jacob' means perception by the Lord regarding the nature of the good of truth. 'And blessed him' means that this good was accordingly joined [to the rational]. 'And commanded him, and said to him' means reflection and consequent perception. 'You shall not take a wife from the daughters of Canaan' means provided it was not joined to affections for falsity and evil. 'Rise up' means provided it raised up that good from these. 'Go to Paddan Aram' means the cognitions of such truth. 'To the home of Bethuel your mother's father, and take for yourself from there a wife from the daughters of Laban your mother's brother' means a parallel external good, and the truth which sprang from this good and was to be joined [to the good of the natural].
