1 Kings 6:15-16

¹⁵He 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. He covered the floor of the house with cypress boards.

¹⁶He built twenty cubits of the back part of the house with boards of cedar from the floor to the ceiling. He built this within, for an inner sanctuary, even for the most holy place.
