1 Kings 6:18-20

Amplified Bible

¹⁸ The cedar on the house within had wood carvings in the shape of gourds and open flowers. Everything was cedar; no stone was visible. ¹⁹ Then he prepared the Holy of Holies within the house in order to put the ark of the covenant of the Lord there. ²⁰ The Holy of Holies was twenty cubits in length, twenty cubits in width, and twenty cubits in height (a cube), and he overlaid it with pure gold. He also overlaid the cedar altar [with gold].
