Parallel
Ezekiel 40:10
Brenton's English Septuagint · Berean Standard Bible
and the chambers of the gate of the chamber in front [were] three on one side and three on the other, and [there was] one measure to the three: [there was] one measure to the porches on this side and on that.
There were three gate chambers on each side of the east gate, each with the same measurements, and the gateposts on either side also had the same measurements.
