Genesis 11:3-4

3They said to one another, “Come, let us make bricks and burn them thoroughly.” And they used brick for stone, and they used 1tar for mortar.

4They said, “Come, let us build for ourselves a city, and a tower whose top 2will reach into heaven, and let us make for ourselves 3a name, otherwise we 4will be scattered abroad over the face of the whole earth.”
