'Holies' in the Bible

Against the wall of the house he built extensions around the walls of the house, around both the main room (Holy Place) and the Holy of Holies; and he made side chambers all around.

He built the walls of the interior of the house [that is, the Holy Place and the Holy of Holies] with boards of cedar, from the floor of the house to the rafters of the ceiling. He overlaid the interior with wood, and he overlaid the floor of the house with boards of cypress.

And he buildeth the twenty cubits on the sides of the house with ribs of cedar, from the floor unto the walls; and he buildeth for it within, for the oracle, for the holy of holies.

The [rest of the] house, that is, the temple in front of the Holy of Holies, was forty cubits long.

Then he prepared the Holy of Holies within the house in order to put the ark of the covenant of the Lord there.

The Holy of Holies was twenty cubits in length, twenty cubits in width, and twenty cubits in height (a cube), and he overlaid it with pure gold. He also overlaid the cedar altar [with gold].

Solomon overlaid the interior of the house with pure gold, and he drew chains of gold across the front of the Holy of Holies (inner sanctuary), and he overlaid it with gold.

Then he overlaid the entire house with gold, until the whole house was finished. He also overlaid the entire [incense] altar which was by the Holy of Holies with gold.

Within the Holy of Holies he made two cherubim (sculptured figures) of olive wood, each ten cubits high.

For the entrance of the Holy of Holies he made two [folding] doors of olive wood, the lintel (header above the door) and five-sided doorposts (frames).

the lampstands of pure gold, five on the right side and five on the left, in front of the Holy of Holies (inner sanctuary); with the flowers, the lamps, and the tongs of gold;

and the basins, and the snuffers, and the bowls, and the spoons, and the censers, of refined gold, and the hinges for the doors of the inner-house, for the holy of holies, for the doors of the house of the temple, of gold.

And the priests bring in the ark of the covenant of Jehovah unto its place, unto the oracle of the house, unto the holy of holies, unto the place of the wings of the cherubs;

The poles were so long that the ends of the poles were visible from the Holy Place that was in front of the Holy of Holies, but they were not visible from the outside; they are there to this day (the date of this writing).
