Then he built the twenty-cubit room at the rear of the temple, from floor to ceiling, with cedar boards; he built it inside as the inner sanctuary, as the Most Holy Place.
And he made the Most Holy Place. Its length was according to the width of the house, twenty cubits, and its width twenty cubits. He overlaid it with six hundred talents of fine gold.
Then the priests brought in the ark of the covenant of the Lord to its place, into the inner sanctuary of the temple, to the Most Holy Place, under the wings of the cherubim.
and the Lord said to Moses: “Tell Aaron your brother not to come at just any time into the Holy Place inside the veil, before the mercy seat which is on the ark, lest he die; for I will appear in the cloud above the mercy seat.
Against the wall of the temple he built chambers all around, against the walls of the temple, all around the sanctuary and the inner sanctuary. Thus he made side chambers all around it.
