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.

Generally in the Bible a "country" means a political subdivision ruled by a king, or sometimes a tribe with a territory ruled by a king or chieftain. Others are what we now call city-states, with surrounding farm areas. In almost all cases these countries were far smaller than our modern idea of countries, though Egypt and Assyria would be exceptions. Sometimes the word is used to refer to countryside, a wide area with no consideration of boundaries as when the twelve Israelites were sent to spy out the country.
