1 Kings 6:15-16

15Then he 1built the walls of the house on the inside with boards of cedar; from the floor of the house to the 2ceiling he overlaid the walls on the inside with wood, and he overlaid the floor of the house with boards of cypress.

163He built twenty cubits on the rear part of the house with boards of cedar from the floor to the 4ceiling; he built them for it on the inside as an inner sanctuary, even as 5the most holy place.
