Thematic Bible: Building the ark of noah

"Make yourself an ark of gofer wood. Make rooms in the ark, and cover it with pitch inside and outside. This is how you are to make it: The ark will be 450 feet long, 75 feet wide, and 45 feet high. You are to make a roof, finishing [the sides of the ark] to within 18 inches [of the roof.] You are to put a door in the side of the ark. Make it with lower, middle, and upper [decks].
