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.

It was 14 feet across, with supporting columns 3½ feet thick. This entry room was at the inner end of the gateway structure, facing toward the Temple.

And he measured the portico of the gate as eight cubits, and its pilaster was two cubits thick, and he measured the portico of the gate on the inside.

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