'Roof' in the Bible

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.

See now, I have two virgin daughters. Please let me bring them out to you, and you may do to them what seems good to you. Only don't do anything to these men, because they have come under the shadow of my roof."
