Genesis 6:13-15

So God said to Noah, “I have decided that all living creatures must die, for their violence has filled the earth, and I will wipe them off the face of the earth! Build a boat for yourself—an ark of sturdy timber. And this is how you are to design it: make separate compartments within it, and seal it inside and out with thick tar. The length is to be 450 feet, its width 75 feet, and its height 45 feet.
