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.

1686. 'Four kings with five' means the union existing with the latter four and the lack of union with the other five. This becomes clear from the meaning of 'four' and from the meaning of 'five'. Consisting of two pairs, 'four' means union, as also does two when it has regard to things that are married, as also noted in 720. 'Five' however means disunity because it is associated with fewness, as shown in 649. All things depend for their particular meanings on the subjects to which they refer.
