Genesis 11:1-6

1And the whole earth had one language, and the same words.

2And it came to pass as they journeyed from the east, that they found a plain in the land of Shinar, and dwelt there.

3And they said one to another, Come on, let us make bricks, and burn [them] thoroughly. And they had brick for stone, and they had asphalt for mortar.

4And they said, Come on, let us build ourselves a city and a tower, the top of which [may reach] to the heavens; and let us make ourselves a name, lest we be scattered over the face of the whole earth.

5And Jehovah came down to see the city and the tower which the children of men built.

6And Jehovah said, Behold, the people is one, and have all one language; and this have they begun to do. And now will they be hindered in nothing that they meditate doing.
