1 Kings 6:20-22

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.
