Ezekiel 40:25-27

25Both 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.

26And 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.

27And there was a gate on the south of the inner court. And he measured from gate to gate toward the south, a hundred cubits.
