Ezekiel 40:10-14

The guardrooms of the gate toward the east numbered three on each side; the three of them had the same measurement. The side pillars also had the same measurement on each side.

And he measured the width of the gateway, ten cubits, and the length of the gate, thirteen cubits.

There was a barrier wall one cubit wide in front of the guardrooms on each side; and the guardrooms were six cubits square on each side.

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.
