Ezekiel 40:13-15

13Then he measured the gate from the ceiling of the one side room to the ceiling of the other, a breadth of twenty-five cubits; the openings faced each other.

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.
