Genesis 11:1-9 (NRSV)
1 Now the whole earth had one language and the same words. 2 And as they migrated from the east, they came upon a plain in the land of Shinar and settled there. 3 And they said to one another, “Come, let us make bricks, and burn them thoroughly.” And they had brick for stone, and bitumen for mortar. 4 Then they said, “Come, let us build ourselves a city, and a tower with its top in the heavens, and let us make a name for ourselves; otherwise we shall be scattered abroad upon the face of the whole earth.” 5 The Lord came down to see the city and the tower, which mortals had built. 6 And the Lord said, “Look, they are one people, and they have all one language; and this is only the beginning of what they will do; nothing that they propose to do will now be impossible for them. 7 Come, let us go down, and confuse their language there, so that they will not understand one another’s speech.” 8 So the Lord scattered them abroad from there over the face of all the earth, and they left off building the city. 9 Therefore it was called Babel, because there the Lord confused the language of all the earth; and from there the Lord scattered them abroad over the face of all the earth.
