Genesis 11:1-8

Now the whole earth spoke one language and used the same words (vocabulary). And as people journeyed eastward, they found a plain in the land of Shinar and they settled there. [Gen 10:10] They said one to another, “Come, let us make bricks and fire them thoroughly [in a kiln, to harden and strengthen them].” So they used brick for stone [as building material], and they used tar (bitumen, asphalt) for mortar. They said, “Come, let us build a city for ourselves, and a tower whose top will reach into the heavens, and let us make a [famous] name for ourselves, so that we will not be scattered [into separate groups] and be dispersed over the surface of the entire earth [as the LORD instructed].” [Gen 9:1] Now the LORD came down to see the city and the tower which the sons of men had built. And the LORD said, “Behold, they are one [unified] people, and they all have the same language. This is only the beginning of what they will do [in rebellion against Me], and now no evil thing they imagine they can do will be impossible for them. Come, let Us (Father, Son, Holy Spirit) go down and there confuse and mix up their language, so that they will not understand one another’s speech.” So the LORD scattered them abroad from there over the surface of the entire earth; and they stopped building the city.
