2 Chronicles 3:7-11

He also overlaid the house with gold—the beams, the thresholds, and its walls and doors; and he carved cherubim on the walls.

Then he made the room of the Most Holy Place: its length across the width of the house was twenty cubits, and its width was twenty cubits; and he overlaid it with fine gold, amounting to six hundred talents.

The weight of the nails was fifty shekels of gold. He also overlaid the upper rooms with gold.

Then he made two sculptured cherubim in the room of the Most Holy Place and overlaid them with gold.

The wingspan of the cherubim was twenty cubits; the wing of one, of five cubits, touched the wall of the house, and its other wing, of five cubits, touched the wing of the other cherub.
