Ezekiel 40:14-16

14He made also posts of sixty cubits, even to the post of the court around to the gate. 15And from the face of the gate of the entrance to the face of the porch of the inner gate were fifty cubits. 16And there were narrow windows to the little chambers, and to their posts within the gate on every side, and likewise to the arches: and windows were all around inside: and upon each post were palm trees.123
