Ezekiel 40:6-16

He went into the opening of the gateway facing east, climbed the steps, and measured its threshold as one reed deep. Beyond the threshold was a corridor, which had rooms on each side for the guards. Each of the side rooms was square and measured one reed on each side. The space between the side rooms was five cubits. And the inside threshold of the gate leading to the portico facing the temple was one reed deep. Then he measured the porch of the gate on the inside. It was eight cubits deep, flanked by pillars two cubits thick. The porch opened onto the temple courtyard. On each side of the east gate there were three guardrooms, all three the same size, and the walls that separated them were the same size. He measured the width of the entrance as ten cubits and its length, thirteen cubits. And there was a low wall one cubit high in front of the guardrooms. Each of the guardrooms was six cubits square. Then he measured the width of the gate from the top back wall of one guardroom to the top back wall of the opposite one. It was twenty-five cubits straight across. He calculated the height of the porch, which led out to a courtyard, as sixty cubits high. From the outside wall of the gate to the far side of the porch, he measured as fifty cubits. On all the inside walls of the gateway were windows with narrow recesses all around. The walls of the guardrooms, the walls between them, and the walls of the porch likewise had windows all around. And there were palm trees carved on the inner walls of the corridor and on the doorways.
