John Gill Commentary Ezekiel 41:26

"And there were closed windows and palm-trees on the one side and on the other side, on the sides of the porch: thus were the side-chambers of the house, and the thresholds." — Ezekiel 41:26 (ASV)

And there were narrow windows See (Ezekiel 41:16) (40:16) : and palm trees on the one side and on the other side, on the sides of the porch ; upon the posts that were on each side the porch, north and south; (Ezekiel 40:16Ezekiel 40:26) : and upon the side chambers of the house, and thick planks ; that is, there were palm trees upon the side chambers, which were in number thirty, (Ezekiel 41:6) and upon the planks also; every part of this fabric within and without were ornamented.
