ASV notes on Genesis 11:8-9
Understanding the words correctly keeps people together and prevents misunderstandings. To have schools for children learning to write and read makes they prepared for their future life in peace and prosperity.
The most important of all things with the understanding of words is the access to God through the Bible. To lead a people without schools for all, is a crime against God’s intention of creating man.
By giving people different languages He spread them and gave them a chance to fulfil His order for them, to fill the earth. From this not finished city of Babel in the middle of the huge plain of Shinar all the people that lived on earth was spread to start their journeys to find their land. The flat area of Shinar is between the two rivers, Euphrates and Tigris. From this place all the people that lived at that time was spread to cover the earth.
