Ezekiel 40:35-37

35Then he brought me to the north gate and measured it. It had the same measurements as the others, 36as did its gate chambers, side pillars, and portico. It also had windows all around. It was fifty cubits long and twenty-five cubits wide. 37Its portico1 faced the outer court, and its side pillars were decorated with palm trees on each side. Eight steps led up to it.
