Ezekiel 40:31-34

31And 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.

32And he brought me into the inner court toward the east: and he measured the gate according to these measures. 33And the little chambers thereof, and the posts thereof, and the arches thereof, were according to these measures: and there were windows therein and in the arches thereof round about: it was fifty cubits long, and five and twenty cubits broad. 34And the arches thereof were toward the outward court; and palm trees were upon the posts thereof, on this side, and on that side: and the going up to it had eight steps.
