Genesis 11

Men repopulate the world and the whole earth has one language but few words.  I didn't pick up on the significance of "but few words".  Does that mean man is in such harmony, nuanced speech is unnecessary?  Anyway, men come from the east and settle in the plain of Shinor.  They baked brick and built a city.  Within the city, they started to builda tower to reach to the heavens.

God comes down (again, he doesn't seem omnipresent yet) to the city and tower.  God is worried that if they complete the tower, "nothing" will be impossible for "them" (man).  He then calls on "us" to go down and confuse their language and confuse them.  Again, the reference to "us" indicates there is more than one divine being.  More interesting, though, is that if man were able to work together, nothing is impossible.  Including, it seems, becoming a threat to God.  And since God just wiped out almost the entire human race a couple of chapters back, it would seem that he would have a problem on his hands if this were so.  Better get to confusing that language!

The men abandon the city, called Babel.  Also interesting is that in the immediately preceding chapter states that the sons of Ham, Shem and Japeth already have different languages.  Is this story out of place in the chronology, or does this reflect sloppy editing?

The rest of the chapter describes the genealogy of Shem to Abraham.  Terah is the father of Abram and Nahor, who is the father of Lot.  Nahor dies in Ur and Abram and his wife Sarai take in Lot.

Asimov says the names of the descendant's of Noah's sons represent tribes or nations.  The descendants of Shem occupy the Arabian peninsula.  "Semetic", the name of the languages these people speak derive from the Greek/Latin name for Shem. Ham's people settle in the corner of Africa nearest Asia and speak Hamatic languages.  Japeth's people settle to the northeast of the Tigris/Euphrates.
