Holy of Holies was Called The: Oracle

Against the walls of the temple and the inner sanctuary, Solomon built a chambered structure around the temple, in which he constructed the side rooms.

He partitioned off the twenty cubits at the rear of the temple with cedar boards from floor to ceiling to form within the temple an inner sanctuary, the Most Holy Place.

The inner sanctuary was twenty cubits long, twenty cubits wide, and twenty cubits high. He overlaid the inside with pure gold, and he also overlaid the altar of cedar.
