Hesekiel 40:21

Också den hade tre vaktkamrar på var sida samt pelare och förhus, lika stora som den förra portens. Den var femtio alnar lång och tjugofem alnar bred.

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.
