The whole earth once shared one language and the same words. As people moved eastward, they found a plain in the land of Shinar and settled there. They learned to bake bricks in place of stone and used bitumen for mortar.
They decided to build a city and a tower reaching toward the heavens. They wanted to make a name for themselves and prevent their people from being scattered over the earth. Their common language allowed them to organize the work together.
God came down to see the city and tower. He observed that they were one people with one language and that this was only the beginning of what they intended to do. God confused their speech so that they could no longer understand one another.
The project included both a city and a tower. Its builders described the tower as reaching into the heavens, but the passage gives no measurement and does not call it a place of worship. They stated their own aims: make a name for themselves and resist being dispersed. The technology, common speech, and shared location all served that decision.
Once their speech was confused, people working beside one another could no longer coordinate. Their attempt to avoid dispersion produced the very result they feared. Babel became a name associated not with a completed monument but with confused speech, abandoned construction, and people moving out across the earth.
Unable to cooperate, the people stopped building the city. The place was called Babel, a name associated with the confusion of their language. From there God scattered them across the earth. The city they had planned together remained unfinished.
