Ezekiel 40:6-7

6Then came he unto the gate which looketh toward the east, and went up the stairs thereof, and measured the threshold of the gate, which was one reed broad; and the other threshold of the gate, which was one reed broad.1 7And every little chamber was one reed long, and one reed broad; and between the little chambers were five cubits; and the threshold of the gate by the porch of the gate within was one reed.
