1 Kings 6:18-22

And the cedar of the house within was carved with knops and open flowers: all was cedar; there was no stone seen.

And the oracle he prepared in the house within, to set there the ark of the covenant of the LORD.

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.
