Ezekiel 40:13-15

13He measured the gate from the roof of one guardroom to the roof of the other, a width of twenty-five cubits from one door to the opposite door.

14He made [the measurement of] the side pillars sixty cubits high; the gate extended all around to the side pillar of the courtyard.

15From the front of the entrance gate [on the outside] to the front of the inner porch (portico) of the gate [the distance] was fifty cubits.
