'Most Holy Place' in the Bible

He lined 20 cubits of the rear part of the Temple from floor to ceiling with cedar boards specially constructed for the inside to serve as the Most Holy Place.

and the cups, snuffers, bowls, spoons, and the fire pans, all made of pure gold, and hinges for the doors of the inner sanctuary, the Most Holy Place, and for the gates of the Temple that led to the nave, also of gold.

After this, the priests brought the Ark of the Covenant of the LORD to the place prepared for it, into the inner sanctuary of the Temple, under the wings of the cherubim in the Most Holy Place.
