Ezekiel 40:6-9

6Then he went into the gateway facing east, going up its steps, and measured the threshold of the gate, one reed deep.

7And the side rooms, one reed long and one reed broad; and the space between the side rooms, five cubits; and the threshold of the gate by the vestibule of the gate at the inner end, one reed.

8Then he measured the vestibule of the gateway, on the inside, one reed.

9Then he measured the vestibule of the gateway, eight cubits; and its jambs, two cubits; and the vestibule of the gate was at the inner end.
