Ezekiel 42:6-8

New International Version

⁶ The rooms on the top floor had no pillars, as the courts had; so they were smaller in floor space than those on the lower and middle floors. ⁷ There was an outer wall parallel to the rooms and the outer court; it extended in front of the rooms for fifty cubits. ⁸ While the row of rooms on the side next to the outer court was fifty cubits long, the row on the side nearest the sanctuary was a hundred cubits long.
