2 Chronicles 3:6-8

6He adorned the temple with precious stones for beauty, and the gold was the gold of Parvaim.

7He overlaid the temple — the beams, the thresholds, its walls and doors — with gold, and he carved cherubim on the walls.

8Then he made the most holy place; its length corresponded to the width of the temple, 30 feet, and its width was 30 feet. He overlaid it with forty-five thousand pounds of fine gold.
