Ezekiel 40:28-31

Then he brought me to the inner court through the southern gateway; he measured the southern gateway according to these same measurements. Also its gate chambers, its gateposts, and its archways were according to these same measurements; there were windows in it and in its archways all around; it was fifty cubits long and twenty-five cubits wide. There were archways all around, twenty-five cubits long and five cubits wide. Its archways faced the outer court, palm trees were on its gateposts, and going up to it were eight steps.
