Genesis 11:1-9 - The Tower Of Babylon
1 And all the world was of one tongue and one language. 2 And as they came from the east, they found a plain in the land of Shinar, and there they dwelled. 3 And they said, one to another, "Come on, let us make brick and burn it with fire." So brick was their stone and slime was their mortar. 4 And they said, "Come on, let us build us a city and a tower, that the top may reach unto heaven. And let us make us a name, for peradventure we shall be scattered abroad over all the earth."
5 And the LORD came down to see the city and the tower which the children of Adam had built. 6 And the LORD said, "See, the people is one and have one tongue among them all: And this have they begun to do, and will not leave off from all that they have purposed to do. 7 Come on, let us descend and mingle their tongue even there, that one understand not what another sayeth." 8 Thus the LORD scattered them from thence upon all the earth. And they left off to build the city. 9 Wherefore the name of it is called Babel, because that the LORD there confounded the tongue of all the world; and because that the LORD, from thence, scattered them abroad upon all the earth.
