Ezekiel 40:24-27

And he led me toward the south, and behold, there was a gate on the south. And he measured its jambs and its vestibule; they had the same size as the others. Both it and its vestibule had windows all around, like the windows of the others. Its length was fifty cubits, and its breadth twenty-five cubits. And there were seven steps leading up to it, and its vestibule was before them, and it had palm trees on its jambs, one on either side. And there was a gate on the south of the inner court. And he measured from gate to gate toward the south, a hundred cubits.
