6:16 He built a wall 30 feet in from the rear of the temple as a partition for an inner sanctuary that would be the most holy place. He paneled the wall with cedar planks from the floor to the rafters.
6:17 The main hall in front of the inner sanctuary was 60 feet long.
6:18 The inside of the temple was all cedar and was adorned with carvings of round ornaments and of flowers in bloom. Everything was cedar; no stones were visible.
