2 Chronicles 3:7-9

So he lined the house with gold—its beams, its thresholds, its walls, and its doors—and he carved cherubim on the walls. And he made the Most Holy Place. Its length, corresponding to the breadth of the house, was twenty cubits, and its breadth was twenty cubits. He overlaid it with 600 talents of fine gold. The weight of gold for the nails was fifty shekels. And he overlaid the upper chambers with gold.
