1 Kings 6:19-22

19And the inner sanctuary he prepared in the inside of the house, to set there the ark of the covenant of the LORD. 20And the inner sanctuary in the forepart was twenty cubits in length, and twenty cubits in breadth, and twenty cubits in the height of it: and he overlaid it with pure gold; and so covered the altar which was of cedar.1 21So Solomon overlaid the inside of the house with pure gold: and he made a partition by the chains of gold before the inner sanctuary; and he overlaid it with gold. 22And the whole house he overlaid with gold, until he had finished all the house: also the whole altar that was by the inner sanctuary he overlaid with gold.
