1 Kings 6:11-13
11-13The word of God came to Solomon saying, "About this Temple you are building—what's important is that you live the way I've set out for you and do what I tell you, following my instructions carefully and obediently. Then I'll complete in you the promise I made to David your father. I'll personally take up my residence among the Israelites—I won't desert my people Israel."
14-18Solomon built and completed The Temple. He paneled the interior walls from floor to ceiling with cedar planks; for flooring he used cypress. The thirty feet at the rear of The Temple he made into an Inner Sanctuary, cedar planks from floor to ceiling—the Holy of Holies. The Main Sanctuary area in front was sixty feet long. The entire interior of The Temple was cedar, with carvings of fruits and flowers. All cedar—none of the stone was exposed.
