Ezekiel 41:15-16

15Next he measured the length of the building facing the temple courtyard at the rear of the temple, including its galleries on each side; it was a hundred cubits. The outer sanctuary, the inner sanctuary, and the porticoes facing the court, 16as well as the thresholds and the beveled windows and the galleries all around with their three levels opposite the threshold, were overlaid with wood on all sides. They were paneled from the ground to the windows, and the windows were covered.
