1 Kings 6:20-22

201The inner sanctuary was twenty cubits in length, twenty cubits in width, and twenty cubits in height; and he overlaid it with pure gold. He also paneled the altar with cedar. 21So Solomon overlaid the inside of the house with pure gold. And he extended chains of gold across the front of the inner sanctuary, and he overlaid it with gold. 22He overlaid the entire house with gold, until all the house was finished. Also 2the entire altar which was by the inner sanctuary he overlaid with gold.
