14 Build a boat of cypress wood for yourself. Make rooms in it and cover it inside and outside with tar.

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.
