Genesis 11:3-4 ▼

3 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.

4 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.”
