Genesis 6:15-17

This is how big I want you to build the boat: four hundred fifty feet long, seventy-five feet wide, and forty-five feet high. Make an opening around the top of the boat that is eighteen inches high from the edge of the roof down. Put a door in the side of the boat. Make an upper, middle, and lower deck in it. I will bring a flood of water on the earth to destroy all living things that live under the sky, including everything that has the breath of life. Everything on the earth will die.
