Ezekiel 40:8-10

New King James Version

⁸ He also measured the vestibule of the inside gate, one rod. ⁹ Then he measured the vestibule of the gateway, eight cubits; and the gateposts, two cubits. The vestibule of the gate was on the inside. ¹⁰ In the eastern gateway were three gate chambers on one side and three on the other; the three were all the same size; also the gateposts were of the same size on this side and that side.
