The whole earth had one language and was of one speech. As they migrated from the east, it happened that they found a plain in the land of Shinar, and they settled there. They said one to another, Come, lets make bricks, and bake them thoroughly.
They used bricks for stone, and asphalt for mortar. They said, Come, let us build ourselves a city, and a tower whose top reaches the sky. Let us make a name for ourselves, so that we are not scattered across the face of the earth.
That is why its was called Babel, because there Yahweh confused the language of all the earth. From there, Yahweh scattered them abroad across face of the earth.
