1 Kings 6:15-16

15He constructed the walls inside the temple with cedar planks; he paneled the inside with wood from the floor of the temple to the rafters of the ceiling. He covered the temple floor with boards made from the wood of evergreens.

16He 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.
