'Ceiling' in the Bible

And he built the walls of the house within with boards of cedar: from the floor of the house unto the walls of the ceiling, he covered them on the inside with wood; and he covered the floor of the house with boards of fir.

And he built twenty cubits on the hinder part of the house with boards of cedar from the floor unto the walls of the ceiling : he built them for it within, for an oracle, even for the most holy place.
