Ezekiel 41:15-16

15Then he measured the length of the building facing the courtyard at the rear of the temple, including its galleries on each side; it was a hundred cubits. The main hall, the inner sanctuary and the portico facing the court, 16as well as the thresholds and the narrow windows and galleries around the three of them—everything beyond and including the threshold was covered with wood. The floor, the wall up to the windows, and the windows were covered.
