Ezekiel 40:28-31

Then he brought me into the inner court through the south gate, and he measured the south gate; it had the same measurements as the others. Its alcoves, its projecting walls and its portico had the same measurements as the others. The gateway and its portico had openings all around. It was fifty cubits long and twenty-five cubits wide. (The porticoes of the gateways around the inner court were twenty-five cubits wide and five cubits deep.) Its portico faced the outer court; palm trees decorated its jambs, and eight steps led up to it.
