Ezekiel 40:9-13

And he measured the porch of the gate, eight cubits; and its side pillars, two cubits. And the porch of the gate was faced inward.

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.
