Parallel
Ezekiel 42:6
Brenton's English Septuagint · Berean Standard Bible
For they were triple, and they had not pillars like the pillars of the outer ones: therefore they projected from the lower ones and the middle ones from the ground.
For they were arranged in three stories, and unlike the courts, they had no pillars. So the upper chambers were set back further than the lower and middle floors.
