These are the generations of Shem: Shem was an hundred years old, and begat Arphaxad two years after the flood. And Shem lived after he begat Arphaxad five hundred years, and begat sons and daughters… And Nahor lived nine and twenty years, and begat Terah: And Nahor lived after he begat Terah an hundred and nineteen years, and begat sons and daughters. And Terah lived seventy years, and begat Abram, Nahor, and Haran. Now these are the generations of Terah: Terah begat Abram, Nahor, and Haran; and Haran begat Lot. And Haran died before his father Terah in the land of his nativity, in Ur of the Chaldees. And 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. But Sarai was barren; she had no child. And 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. And the days of Terah were two hundred and five years: and Terah died in Haran.(Genesis 11:10-32)
The second half of Genesis 11, is a transitional chapter. The LORD had by then allowed for a brief period of innocence, (Adam and Eve) which ended in a fall. He then allowed men to develop without any human government, in a time when there were two distinct streams of humanity, believing and unbelieving, (Seth and Cain,and the pre-flood civilization) but this era ended with a massive apostasy and a worldwide flood.
Finally, the Lord allowed for an age of total unity, in which the whole world had one culture, one language, and one calling, to fill the earth. The human governments that God had established after the flood, degenerated into tyranny, the rise of a proto anti-Christ(Nimrod), and a globalist project to disavow God.
The Divine focus will now shift from a universal dealing with all of the nations of the world, to an individual from the tribe of Shem, a man named Abram. This Shemite, lived in Ur of the Chaldees, several generations from the Babel incident. At the time of his election, Abram was an idolater, with His father Terah, and brother Nahor.
And Joshua said unto all the people, Thus saith the Lord God of Israel, Your fathers dwelt on the other side of the flood in old time, even Terah, the father of Abraham, and the father of Nachor: and they served other gods. And I took your father Abraham from the other side of the flood, and led him throughout all the land of Canaan, and multiplied his seed, and gave him Isaac.( Joshua 24:2-3)
God would create a new, priestly nation, a witness of His truth and Salvation to the ends of the earth.
But when the God of the Bible wanted to create a brand new nation by which to witness to and save the world, he didn’t choose a virile young couple in the prime of life. Rather He chose an elderly married couple, who had gone long past child bearing age, and had never been able to have children.
A full, Divinely wrought Salvation for all mankind would require a miracle, so the LORD by a miracle created a “Holy Nation”. God “gives life to the dead, and calls those things which be not, as though they were…”. He chose Abram and Sarai, to be the “Father ( and mother) of a multitude”, and through whom would come a seed who would bless all of the families of the earth!
The Divine dealings with Abraham and his miracle family, are the theme of the rest of Genesis and shape the development of all of subsequent human history. Salvation is of the Jews, the seed of Abraham,Isaac and Jacob, and leads man to the first and second coming of the Messiah, the seed of the woman, and the seed of Abraham, Jesus Christ!
