Genesis 11:1-9

Now the entire earth had the same language with the same vocabulary. When they traveled eastward, they found a valley-plain in the land of Shinar and settled there. They said to one another, “Come! Let’s make bricks and bake them until they’re hard.” So they used bricks for stone, and tar for mortar. Then they said, “Come! Let’s build ourselves a city, with a tower whose top reaches into heaven. So let’s make a name for ourselves, or else we will be scattered over the face of the whole land.” Then ADONAI came down to see the city and the tower that the sons of man had built. ADONAI said, “Look, the people are one and all of them have the same language. So this is what they have begun to do. Now, nothing they plan to do will be impossible. Come! Let Us go down and confuse their language there, so that they will not understand each other’s language.” So ADONAI scattered them from there over the face of the entire land, and they stopped building the city. This is why it is named Babel, because ADONAI confused the languages of the entire world there, and from there ADONAI scattered them over the face of the entire world.
