Arcana Coelestia #47
47. That these words contain arcana concerning regeneration becomes additionally clear from the fact that verse 24 above spoke of the earth bringing forth 'living creatures, beasts, and wild animals of the earth', while in the verse that followed the order was different, namely that God made the wild animals of the earth first and then the beasts. Indeed a person does first produce things so to speak from himself, and continues to do so until he becomes celestial. And so regeneration begins with the external man and moves on to the internal. This is why there is a different order here, with external things coming first.
Arcana Coelestia #2648
2648. 'Abraham made a great feast' means dwelling together and union. This is clear from the meaning of 'a feast' as dwelling together, dealt with in 2341. Here union is meant as well since the subject is the Lord, whose Human was united to the Divine, and the Divine to the Human. And because this union is the subject it is called 'a great feast'.
