Thematic Bible: Building the ark of noah

'Make for thyself an ark of gopher-wood; rooms dost thou make with the ark, and thou hast covered it within and without with cypress; and this is that which thou dost with it: three hundred cubits is the length of the ark, fifty cubits its breadth, and thirty cubits its height; a window dost thou make for the ark, and unto a cubit thou dost restrain it from above; and the opening of the ark thou dost put in its side, -- lower, second, and third stories dost thou make it.
