Context Reading
8So the LORD scattered them from there over the face of all the earth, and they stopped building the city. 9That is why it is called Babel, for there the LORD confused the language of the whole world, and from that place the LORD scattered them over the face of all the earth. 10This is the account of Shem. Two years after the flood, when Shem was 100 years old, he became the father of Arphaxad. 11And after he had become the father of Arphaxad, Shem lived 500 years and had other sons and daughters. 12When Arphaxad was 35 years old, he became the father of Shelah.
