Ezekiel 40:20

And the pavement by the side of the gates over against the length of the gates [was] the lower pavement.

Then he measured the breadth from the forefront of the lower gate unto the forefront of the inner court without, an hundred cubits eastward and northward.

And the little chambers thereof [were] three on this side and three on that side; and the posts thereof and the arches thereof were after the measure of the first gate: the length thereof [was] fifty cubits, and the breadth five and twenty cubits.

And their windows, and their arches, and their palm trees, [were] after the measure of the gate that looketh toward the east; and they went up unto it by seven steps; and the arches thereof [were] before them.
