Ezekiel 40:16

And there were narrow windows to the little chambers, small latticed openings for light, slanting inward from the outside of the wall, so as to offer as much light as possible, and to their posts within the gate round about, pillars projecting from the walls enclosing these windows, and likewise to the arches, or galleries; and windows were round about inward, on the walls of the passage and in the cells, so that they could be seen, no matter which way a person turned; and upon each post were palm-trees, ornaments having the shape of palm-trees.
