Four
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.

Jeremiah 31:27-28
27
Behold, the days come, says Yahweh, that I will sow the house of Israel and the house of Judah with the seed of man, and with the seed of animal.
28
It shall happen that, like as I have watched over them to pluck up and to break down and to overthrow and to destroy and to afflict, so will I watch over them to build and to plant, says Yahweh.
