Ezekiel 40:9

Then 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 .

it was eight cubits deep and its jambs were two cubits thick. The portico of the gateway faced the temple.

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