Genesis 6:15-17

This is how you will build the ship: It must be 150 metres long, 25 metres wide and 15 metres high. Make a roof for the ship. Leave a space 45 centimetres high all round under the roof. Put a door in the side of the ship. Inside the ship, make three floors above each other. I will cover the earth with deep water. I will destroy all living things, wherever they live. Everything that breathes will die.
