Genesis 11:5-7

And the LORD came down to see the city and the tower, which the children of man had built. And the LORD said, “Behold, they are one people, and they have all one language, and this is only the beginning of what they will do. And nothing that they propose to do will now be impossible for them. Come, let us go down and there confuse their language, so that they may not understand one another’s speech.”
