Ezekiel 42:7-9

New International Version

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. ⁹ The lower rooms had an entrance^(A) on the east side as one enters them from the outer court.
