Ezekiel 40:14-16

14And he made posts, sixty cubits, and by the post was the court of the gate round about.

15And from the front of the gate of the entrance unto the front of the porch of the inner gate were fifty cubits.

16And there were closed windows to the chambers, and to their posts within the gate round about, and likewise to the projections; and the windows round about were inward; and upon [each] post were palm-trees.
