'Ceiling' in the Bible

He built the walls of the house within with boards of cedar: from the floor of the house to 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.

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