15 He lined the walls of the house on the inside 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 cypress.

16 He built twenty cubits of the rear of the house with boards of cedar from the floor to the walls, and he built this within as an inner sanctuary, as the Most Holy Place.
