1 Kings 6:14-17

14So Solomon built the temple and finished it.

15And he built the inside walls of the temple with cedar boards; from the floor of the temple to the ceiling he paneled the inside with wood; and he covered the floor of the temple with planks of cypress.

16Then he built the twenty-cubit room at the rear of the temple, from floor to ceiling, with cedar boards; he built it inside as the inner sanctuary, as the Most Holy Place.

17And in front of it the temple sanctuary was forty cubits long.
