15 This is how big I want you to build the boat: 450 feet long, 75 feet wide and 45 feet high.

16 Make an opening around the top of the boat. Make it 18 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.

17 I will bring a flood of water on the earth. I will destroy all living things that live under the sky. This includes everything that has the breath of life. Everything on the earth will die.
