Ezekiel 40:9-13

9Then he measured the porch of the gate, eight cubits, and its side pillars, two cubits. The porch of the gate faced inward [toward the temple of the Lord].

10There were three guardrooms on each side of the gate toward the east; the three were the same size, and the side pillars on each side measured the same.

11And he measured the width of the gateway, ten cubits, and the length of the gate, thirteen cubits.

12On each side a border (barrier wall) one cubit wide stood in front of the guardrooms on each side; and the guardrooms were six cubits square on each side.

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.
