According to the story, a united human race speaking a single language and migrating eastward, comes to the land of Shinar (שִׁנְעָר; Σενναάρ). There they agree to build a city and a tower with its top in the sky. Yahweh, observing their city and tower, confounds their speech so that they can no longer understand each other, and scatters them around the world.
