Ezekiel 40:15-16

And from the face of the gate, &c. The whole length of the porch, from the outward front unto the inner side, which looked into the first court, was fifty cubits. There were narrow windows to the little chambers, &c. Every one of these little chambers (Eze 40:7) had a narrow window to it, toward the inside of the gate where the passage was; and so there was over the side-posts or fronts placed at the entrance of every chamber; and likewise to the arches The word translated arches signifies also a porch, or entrance; and the word being so taken, the sense is, that there was a window over every door. And upon each post were palm-trees A palm-tree was carved upon the chapiter of each side-post, or front.
