1 Kings 6:22 (KJV)

And the oracle in the forepart was twenty cubits in length, and twenty cubits in breadth, and twenty cubits in the height thereof: and he overlaid it with pure gold; and so covered the altar which was of cedar.

So Solomon overlaid the house within with pure gold: and he made a partition by the chains of gold before the oracle; and he overlaid it with gold.

And the whole house he overlaid with gold, until he had finished all the house: also the whole altar that was by the oracle he overlaid with gold.

And within the oracle he made two cherubims of olive tree, each ten cubits high.

And five cubits was the one wing of the cherub, and five cubits the other wing of the cherub: from the uttermost part of the one wing unto the uttermost part of the other were ten cubits.
