Ezekiel 40:13-17

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

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

And from the front of the entrance gate to the front of the inner porch of the gate was fifty cubits.

And there were shuttered windows looking toward the guardrooms, and toward their side pillars within the gate all around, and likewise for the porches. And there were windows all around inside; and on each side pillar were palm tree decorations.

Then he brought me into the outer courtyard, and behold, there were chambers and a stone pavement made for the courtyard all around; thirty chambers faced the pavement.
