Ezekiel 40:6-9

6Then he went to the gateway which faced east; and he went up its stairs and measured the threshold of the gateway, which was one rod wide, and the other threshold was one rod wide.

7Each gate chamber was one rod long and one rod wide; between the gate chambers was a space of five cubits; and the threshold of the gateway by the vestibule of the inside gate was one rod.

8He also measured the vestibule of the inside gate, one rod.

9Then he measured the vestibule of the gateway, eight cubits; and the gateposts, two cubits. The vestibule of the gate was on the inside.
