1 Kings 6:16

And he built the twenty cubits from the top of the wall, one side from the floor to the beams, and he made it from the oracle to the most holy place.

And he built twenty cubits on the sides of the house, both the floor and the walls with boards of cedar: he even built them for it within, even for the oracle, even for the most holy place.

He 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.
