Genesis 6:16

Thou shalt narrow the ark in making it, and in a cubit above thou shalt finish it, and the door of the ark thou shalt make on the side; with lower, second, and third stories thou shalt make it.

A window shalt thou make to the ark, and in a cubit shalt thou finish it above; and the door of the ark shalt thou set in the side thereof; with lower, second, and third stories shalt thou make it.

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.
