Thematic Bible: Building the ark of noah

Make a ship of gopher wood. You shall make rooms in the ship, and shall seal it inside and outside with pitch. This is how you shall make it. The length of the ship will be three hundred cubits, its breadth fifty cubits, and its height thirty cubits. You shall make a roof in the ship, and you shall finish it to a cubit upward. You shall set the door of the ship in its side. You shall make it with lower, second, and third levels.
