Ezekiel 40:35-37

35Then he brought me to the north gateway and measured it according to these same measurements—

36also its gate chambers, its gateposts, and its archways. It had windows all around; its length was fifty cubits and its width twenty-five cubits.

37Its gateposts faced the outer court, palm trees were on its gateposts on this side and on that side, and going up to it were eight steps.
