Hesekiel 40:29

Vaktkamrar, pelare och förhus var lika stora som de andra, och den hade fönster liksom förhuset runt omkring. Den var femtio alnar lång och tjugofem alnar bred.

And the little chambers thereof, and the posts thereof, and the arches thereof, according to these measures: and there were windows in it and in the arches thereof round about: it was fifty cubits long, and five and twenty cubits broad.
