'Ceiling' in the Bible

Then he built the walls of the house on the inside with boards of cedar; from the floor of the house to the ceiling he overlaid the walls on the inside with wood, and he overlaid the floor of the house with boards of cypress.

He built twenty cubits on the rear part of the house with boards of cedar from the floor to the ceiling; he built them for it on the inside as an inner sanctuary, even as the most holy place.
