Genesis 6:14-16

14 Make yourself an[5] ark of[6] gopher wood; make in it rooms (stalls, pens, coops, nests, cages, compartments) and[7] coat it inside and out with pitch (bitumen).

15 This is the way you are to make it: the length of the ark shall be three hundred cubits, its width fifty cubits, and its height thirty cubits (450' x 75' x 45').

16 You shall make a[8] window [for light and ventilation] for the ark, and finish it to at least a cubit (eighteen inches) from the top—and set the [entry] door of the ark in its side; and you shall make it with lower, second and third decks.
