Ezekiel 40:27-31

And there was a gate in the inner court toward the south: and he measured from gate to gate toward the south an hundred cubits.

And he brought me to the inner court by the south gate: and he measured the south gate according to these measures;

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.

And the arches round about were five and twenty cubits long, and five cubits broad.

And the arches thereof were toward the utter court; and palm trees were upon the posts thereof: and the going up to it had eight steps.
