Genesis 11

Genesis 10 gives a geneology of the sons of Noah, which I've skipped.  Moving along to Chapter 11.

Genesis Chapter 11

¹And the whole earth was of one language, and of one speech.

That makes sense since everyone is related.
 

²And it came to pass, as they journeyed from the east, that they found a plain in the land of Shinar; and they dwelt there.

³And they said one to another, Go to, let us make brick, and burn them throughly. And they had brick for stone, and slime had they for morter.

⁴And they said, Go to, let us build us a city and a tower, whose top [may reach] unto heaven; and let us make us a name, lest we be scattered abroad upon the face of the whole earth.

⁵And the LORD came down to see the city and the tower, which the children of men builded.

Why are they building a tower?  It seems they have foreshadowed their own scattering though.  It is interesting that the Lord came down to see the city.  Couldn't he see it from his vantage point?  Didn't he know what the people were doing?
 

⁶And the LORD said, Behold, the people [is] one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do.

Aw man, they are getting too powerful!  
 

⁷Go to, let us go down, and there confound their language, that they may not understand one another's speech.

Because they won't be able to figure out how to understand each other.
 

⁸So the LORD scattered them abroad from thence upon the face of all the earth: and they left off to build the city.

⁹Therefore is the name of it called Babel; because the LORD did there confound the language of all the earth: and from thence did the LORD scatter them abroad upon the face of all the earth.

And know we have the biblical explanation for the origin of multiple languages and different "tribes" across the face of the Earth.  The Lord, he hath confounded us!  What follows is more genealogy that leads us to Abraham and Lot... dum dum dum...

 
¹⁰These [are] the generations of Shem: Shem [was] an hundred years old, and begat Arphaxad two years after the flood:

¹¹And Shem lived after he begat Arphaxad five hundred years, and begat sons and daughters.

¹²And Arphaxad lived five and thirty years, and begat Salah:

¹³And Arphaxad lived after he begat Salah four hundred and three years, and begat sons and daughters.

¹⁴And Salah lived thirty years, and begat Eber:

¹⁵And Salah lived after he begat Eber four hundred and three years, and begat sons and daughters.

¹⁶And Eber lived four and thirty years, and begat Peleg:

¹⁷And Eber lived after he begat Peleg four hundred and thirty years, and begat sons and daughters.

¹⁸And Peleg lived thirty years, and begat Reu:

¹⁹And Peleg lived after he begat Reu two hundred and nine years, and begat sons and daughters.

²⁰And Reu lived two and thirty years, and begat Serug:

²¹And Reu lived after he begat Serug two hundred and seven years, and begat sons and daughters.

²²And Serug lived thirty years, and begat Nahor:

²³And Serug lived after he begat Nahor two hundred years, and begat sons and daughters.

²⁴And Nahor lived nine and twenty years, and begat Terah:

²⁵And Nahor lived after he begat Terah an hundred and nineteen years, and begat sons and daughters.

²⁶And Terah lived seventy years, and begat Abram, Nahor, and Haran.

²⁷Now these [are] the generations of Terah: Terah begat Abram, Nahor, and Haran; and Haran begat Lot.

²⁸And Haran died before his father Terah in the land of his nativity, in Ur of the Chaldees.

²⁹And Abram and Nahor took them wives: the name of Abram's wife [was] Sarai; and the name of Nahor's wife, Milcah, the daughter of Haran, the father of Milcah, and the father of Iscah.

³⁰But Sarai was barren; she [had] no child.

³¹And Terah took Abram his son, and Lot the son of Haran his son's son, and Sarai his daughter in law, his son Abram's wife; and they went forth with them from Ur of the Chaldees, to go into the land of Canaan; and they came unto Haran, and dwelt there.

³²And the days of Terah were two hundred and five years: and Terah died in Haran.
