Genesis 11:5-9

But the LORD came down to look at the city and the tower the people were building. “Look!” he said. “The people are united, and they all speak the same language. After this, nothing they set out to do will be impossible for them! Come, let’s go down and confuse the people with different languages. Then they won’t be able to understand each other.” In that way, the LORD scattered them all over the world, and they stopped building the city. That is why the city was called Babel, because that is where the LORD confused the people with different languages. In this way he scattered them all over the world.
