"The Lord said,'If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them.'<quoted text>
Language is an amazing thing..because in the west even though we speak the same language..its sometimes hard to understand cockney ..or the huge broad accents of the Scots..
I believe that God scattered them..not because he was afraid..but because they were commanded to ' go and multiply'
Instead they were frightened and tried to find protection and security for themselves in a 'city' and building a tower..they actually said ' Let us make a name for ourselves'
Cities are mans way of trying to feel secure with food and water. and amenities..all the things man originally had in the garden of Eden.....
it was Cain that built the first city, as he lost his sense of security , and tried to make it for himself...
The more man becomes a city slicker, the more he loses touch with his environment..and thinks milk and food comes from a super market as his waste.. pollutes the land that produces his food.
If you take it literally "God" was afraid that they would become too powerful.
I take it metaphorically as example of the power of a common language which enables human beings to accomplish tremendous goals when working collectively and the difficulties presented when we do not have a viable means of communicating with each other.
