Genesis 11:1-9

And it happened, in their traveling from the east, that they found a broad valley in the land of Shinar and settled there.

And they said to one another: Come--let's make bricks and bake them in fire. So the bricks served as stoned and pitch served as the mortar for them.

Then they said: Come--let's build for ourselves a city, and a tower with its top in the heavens, and we will make a name for ourselves so that we do not scatter over the face of all of the earth.

And the Lord God descended to look at the city and the tower that the people were building.

Then The Lord said: Look--there is one people and all of them have one language, and this is what they have begun to do. And now nothing that they propose to do will be beyond them.

Come--let's descend and there confuse their language so that they will not understand one another's speech.

So The Lord scattered them from there over the face of all of the earth, and they stopped building the city.

Therefore one called its name Babel, because there The Lord confused the language of all of the earth and from there The Lord scattered them over the face of all of the earth.
