The main idea in Gn 11 is that God saw that human beings were showing sinful pride in their achievements which set them apart from God. The first thing that happened was that the world was resettling. After the flood, everyone was rebuilding something of themselves to be known. Next, God saw they were not reconstructing to better themselves as a community, but rather to accentuate or brag about what they have created. God saw that the people were not creating anything beneficial that would serve others in their community. Finally, the Lord decided to come down and confuses the people so that they would be unable to understand each other because they are all speaking different languages. Then the Lord scattered them all over the world, and they stop building the city. A life lesson we can learn from this passage is to build something that has the purpose to do good for others rather than to brag about yourself.
"The whole world had the same language and the same words. When they were migrating from the east, they came to a valley in the land of Shinar and settled there. They said to one another, “ Come, let us mold bricks and harden them with fire.” They used bricks for stone, and bitumen for mortar. Then they said, “ Come, let us build ourselves a city and a tower with its top in the sky, and so make a name for ourselves; otherwise we shall be scattered all over the earth,” (Gn 11:1-4).
"The Lord came down to see the city and the tower the people had built. Then the Lord said: If now, while they are one people and all have the same language, they have started to do this, nothing they presume to do will be out of their reach. Come, let us go down there confuse their language, so that no one will understand the speech of another," (Gn 11:5-7).
"So the Lord scattered them from there over all the earth, and they stopped building the city," (Gn 11:8).
