Read Genesis 11:3 Using Other Translations
And they said one to another, Go to, let us make brick, and burn them throughly. And they had brick for stone, and slime had they for morter.
And they said to one another, "Come, let us make bricks, and burn them thoroughly." And they had brick for stone, and bitumen for mortar.
They began saying to each other, “Let’s make bricks and harden them with fire.” (In this region bricks were used instead of stone, and tar was used for mortar.)
