'Roof' in the Bible

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.

Look, I’ve got two daughters who haven’t had sexual relations with a man. I’ll bring them out to you, and you can do whatever you want to them. However, don’t do anything to these men, because they have come under the protection of my roof.”
