Parallel
Ezekiel 40:16
Brenton's English Septuagint · Berean Standard Bible
And [there were] secret windows to the chambers, and to the porches within the gate of the court round about, and in the same manner windows to the porches round about within: and on the porch [there were] palm-trees on this side and on that side.
The gate chambers and their side pillars (note: Or gateposts or jambs or projecting walls; here and throughout Ezekiel 40 and 41.) had beveled windows all around the inside of the gateway. The porticos also had windows all around on the inside. Each side pillar was decorated with palm trees.
