The first eleven chapters of Genesis form the prologue for the rest of the Bible. In these chapters we find some of the Bible's most famous stories, like Adam and Eve, Cain and Abel, and Noah's Ark. This prologue culminates with the united people of earth attempting to build a tower to heaven, only for God to confuse their efforts by distributing different languages across the population.
On the surface, it seems like a simple moral story about where the world's languages come from. But the Tower of Babel is one of the most vital Bible stories—because the ancient Jews believed that something even bigger was at play than language. If you understand the Tower of Babel, then you gain a huge advantage when reading anything else in the Old Testament.
Because the Bible's original readers didn't just see the Tower of Babel as the story of how the nations got their languages. They saw it as the moment when the nations got their gods, too.
