Ezekiel 40:27-31

The inner courtyard had a gate toward the south; and he measured from gate to gate toward the south, a hundred cubits.

Then he brought me to the inner courtyard by the south gate; and he measured the south gate according to those same measurements.

Its guardrooms also, its side pillars, and its porches were according to those same measurements. And the gate and its porches had windows all around; it was fifty cubits long and twenty-five cubits wide.

There were porches all around, twenty-five cubits long and five cubits wide.

And its porches were toward the outer courtyard; and palm tree decorations were on its side pillars, and its stairway had eight steps.
