1 Kings 6:16; 1 Kings 6:19; 1 Kings 6:20

16 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.

19 Then he prepared an inner sanctuary within the house in order to place there the ark of the covenant of the LORD .

20 The inner sanctuary was twenty cubits in length, twenty cubits in width, and twenty cubits in height, and he overlaid it with pure gold. He also overlaid the altar with cedar.
