Ezekiel 40:14-16

14He measured also the vestibule, sixty cubits. And around the vestibule of the gateway was the court.

15From the front of the gate at the entrance to the front of the inner vestibule of the gate was fifty cubits.

16And the gateway had windows all around, narrowing inwards toward the side rooms and toward their jambs, and likewise the vestibule had windows all around inside, and on the jambs were palm trees.
