'Most Holy Place' in the Bible

Now he made the room of the Holy of Holies: its length equaling the width of the house was twenty cubits, and its width was twenty cubits; and he overlaid it with 600 talents of fine gold.

And in the Holy of Holies he made two sculptured cherubim, and overlaid them with gold.

He made the veil [between the Holy Place and the Holy of Holies] of blue, purple, and crimson colors, and fine linen, and embroidered cherubim on it.

and the snuffers, the basins, the dishes [for incense], and the firepans, of pure gold; and for the entrance of the house (temple), the inner doors for the Holy of Holies and the doors of the Holy Place (main room), were of gold.
