The Tower of Babel.
Genesis 11:1 Now the earth was of one language and of the same speech.
Genesis 11:2 And when they were advancing from the east, they found a plain in the land of Shinar, and they dwelt in it.
Genesis 11:3 And each one said to his neighbor, “Come, let us make bricks, and bake them with fire.” And they had bricks instead of stones, and pitch instead of mortar.
Genesis 11:4 And they said: “Come, let us make a city and a tower, so that its height may reach to heaven. And let us make our name famous before we are divided into all the lands.”
Genesis 11:5 Then the Lord descended to see the city and the tower, which the sons of Adam were building.
Genesis 11:6 And he said: “Behold, the people are united, and all have one tongue. And since they have begun to do this, they will not desist from their plans, until they have completed their work.
Genesis 11:7 Therefore, come, let us descend, and in that place confound their tongue, so that they may not listen, each one to the voice of his neighbor.”
Genesis 11:8 And so the Lord divided them from that place into all the lands, and they ceased to build the city.
Genesis 11:9 And for this reason, its name was called ‘Babel,’ because in that place the language of the whole earth became confused. And from then on, the Lord scattered them across the face of every region.
