The number "four" in the Bible represents things being linked together or joined. This is partly because four is two times two, and two represents the ultimate linking between our desire to be good and our understanding of truth. We can also see this in the fact that most buildings are rectangular, with the four sides linking together to make a whole. We also divide directions into four -- north, east, south and west -- and talk about the "four corners" of something meaning all of it. So our special thinking naturally looks at four sides as linking together into a whole.

5400. 'And [Jacob] saw' means the things that constitute faith. This is clear from the meaning of 'seeing' as those things that constitute faith, dealt with in 897, 2325, 2807, 3863, 3869, 4403-4421. When it has no link whatsoever with such things as exist in the world, sight - that is, spiritual sight - is nothing else than a perception of truth, that is, of such things as constitute faith. Therefore 'seeing' has no other meaning in the internal sense; for the internal sense emerges when everything of a worldly nature is set aside; for the internal sense concerns itself with the kinds of things that belong to heaven.

[2] The light of heaven which enables one to see there is Divine Truth received from the Lord. This appears before angels' eyes as light a thousand times brighter than the light at midday in the world; and because it holds life within it, that light therefore brings sight to angels' understanding at the same time as it does so to their eyes, imparting a discernment of truth to them which is regulated by the amount and the nature of good present within them. Because this chapter deals in the internal sense with those things that constitute faith, that is, with the truths known to the Church, the verb 'saw' is used at the very beginning of the chapter, 'saw' meaning the things that constitute faith.
