Ezekiel 40:5-9

And behold a wall on the outside of the house round about, and in the man’s hand a measuring reed of six cubits long by the cubit and an hand breadth: so he measured the breadth of the building, one reed; and the height, one reed.

Then 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.

And 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.

He measured also the porch of the gate within, one reed.

Then measured he the porch of the gate, eight cubits; and the posts thereof, two cubits; and the porch of the gate was inward.
