Arcana Coelestia #61
61. Everything that has to do with cognitions of faith is called spiritual, and everything that has to do with love to the Lord and towards the neighbour is called celestial. The former belong to man's understanding, the latter to his will.

2726. That 'Abraham sojourned in the land of the Philistines for many days' means that the Lord allied to the doctrine of faith very many things drawn from a knowledge of human cognitions is clear from the meaning of 'sojourning' as giving instruction, dealt with in 1463, 2025, from the representation of 'Abraham' as the Lord, dealt with in 1965, 1989, 2011, 2501, from the meaning of 'the land of the Philistines' or Philistia as knowledge of cognitions, dealt with in 1197, 1198, and from the meaning of 'days' as the state of whatever it is that is the subject, 23, 487, 488, 493, 893. Here because the subject is the cognitions from which the facts and rational ideas are obtained, and because the expression 'many days' is used, the meaning is relatively 'very many things' From verse 22 onwards the subject has been the rational ideas based on human factual knowledge, which were allied to the doctrine of faith, as is evident from the explanation given. The present verse forms the conclusion to these considerations. As regards the actual subject, since this in itself is rather profound, and since the same subject is dealt with extensively further on, in Chapter 26, let any further explanation here be put off till that chapter.
