Ezekiel 40:14-16

14He made the side pillars sixty cubits high; the gate extended all around to the side pillar of the 1courtyard. 15And from the front of the entrance gate to the front of the inner porch of the gate was fifty cubits. 16And there were 23shuttered windows looking toward the guardrooms, and toward their side pillars within the gate all around, and likewise for the porches. And there were windows all around inside; and on each side pillar were 4palm tree decorations.
