Genesis 11:8-10

Complete Jewish Bible

⁸ So from there Adonai scattered them all over the earth, and they stopped building the city. ⁹ For this reason it is called Bavel [confusion] — because there Adonai confused the language of the whole earth, and from there Adonai scattered them all over the earth.

¹⁰ Here is the genealogy of Shem. Shem was 100 years old when he fathered Arpakhshad two years after the flood.
