2 Chronicles 3:6-8

Amplified Bible

⁶ And he adorned the house with precious stones; and the gold was gold from Parvaim. ⁷ He also overlaid the house [the Holy Place] with gold—the beams, the thresholds, and its walls and its doors; and he carved cherubim on the walls.

⁸ Now he made the room of the Holy of Holies: its length equaling the width of the house was twenty cubits, and its width was twenty cubits; and he overlaid it with 600 talents of fine gold.
