Genesis 11:1-4

Now all the earth used the same language and the same words.

And it came about, as they journeyed east, that they found a plain in the land of Shinar and settled there.

Then they said to one another, “Come, let’s make bricks and fire them thoroughly.” And they used brick for stone, and they used tar for mortar.

And they said, “Come, let’s build ourselves a city, and a tower whose top will reach into heaven, and let’s make a name for ourselves; otherwise we will be scattered abroad over the face of all the earth.”
