'Roof' in the Bible

You are to put a window in the ark, a cubit from the roof, and a door in the side of it, and you are to make it with a lower and second and third floors.

See now, I have two unmarried daughters; I will send them out to you so that you may do to them whatever seems good to you: only do nothing to these men, for this is why they have come under the shade of my roof.
