Confusion
But the Lord came down to see the city and the tower that the men were building. The Lord said, “If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them. Come let us go down and confuse their language so they will not understand one another.” So the Lord scattered them from there over all the earth, and they stopped building the city. That is why it is called Babel – because there the Lord confused the language of the whole world. Gen 11:5-9
