Ezekiel 40:26-30

And there were seven steps to go up to it, and the arches thereof were before them: and it had palm trees, one on this side, and another on that side, upon the posts thereof.

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.
