Genesis 11:4-9 CSB
And they said, “Come, let’s build ourselves a city and a tower with its top in the sky. Let’s make a name for ourselves; otherwise, we will be scattered throughout the earth.”
Then the LORD came down to look over the city and the tower that the humans were building. The LORD said, “If they have begun to do this as one people all having the same language, then nothing they plan to do will be impossible for them. Come, let’s go down there and confuse their language so that they will not understand one another’s speech.” So from there the LORD scattered them throughout the earth, and they stopped building the city. Therefore it is called Babylon, for there the LORD confused the language of the whole earth, and from there the LORD scattered them throughout the earth.
