4 Against 5

The Ramban writes that the battle Avrohom fought with the 4 kings represents that we will survive the 4 stages of exile, עיי"ש.  In this derech remez mode I would like to add בדרך אפשר the following.  As discussed in the past the letter 4 represents division.  5 is the inside of the box, represents the inside of the box, it is the central dot that units all.  The battle of the 4 kings against the 5 kings is the battle of this world seeming separate from Hashem against the the yichud of Hashem that illuminates the world.  The battle represents that ultimately that yichud will become revealed and vanquish the separation that the world seems to be.  The 12 years represent the 12 גבולי אלכסון of the world and the 13 years of rebellion represent the אחד fighting to gain control over the 12 גבולי אלכסון.
