Ezekiel 40:21-22

21And the lodges 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. 22And the windows thereof, and the arches thereof, and the palm-trees thereof, were after the measure of the gate whose prospect is toward the east; and they went up unto it by seven steps; and the arches thereof were before them.
