1 Kings 6:19-23

Then he prepared an inner sanctuary inside the house in order to place there the ark of the covenant of the Lord.

The 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.

So 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.

He overlaid the entire house with gold, until all the house was finished. Also the entire altar which was by the inner sanctuary he overlaid with gold.

And in the inner sanctuary he made two cherubim of olive wood, each ten cubits high.
