Ezekiel 40:14

He measured the width of the opening of the gate, ten cubits; and the length of the gate, thirteen cubits;

and a border before the lodges, one cubit on this side, and a border, one cubit on that side; and the side rooms, six cubits on this side, and six cubits on that side.

He measured the gate from the roof of the one side room to the roof of the other, a width of twenty-five cubits, door against door.

From the forefront of the gate at the entrance to the forefront of the inner porch of the gate were fifty cubits.

There were closed windows to the side rooms, and to their posts within the gate all around, and likewise to the arches. Windows were around inward. Palm trees were on each post.

Then he brought me into the outer court. Behold, there were rooms and a pavement made for the court all around. Thirty rooms were on the pavement.
