Genesis 11:3-4

Leeser(i) 3 And they said to one another, Go to, let us make bricks, and burn them thoroughly. And thus the brick served them for stone, and slime served them for mortar. 4 And they said, Go to, let us build ourselves a city, and a tower, the top of which may reach unto heaven; and let us make ourselves a name, lest we be scattered abroad upon the face of the whole earth.
