Parallel
Ezekiel 41:7
World English Bible British Edition · Berean Standard Bible
The side rooms were wider on the higher levels, because the walls were narrower at the higher levels. Therefore the width of the house increased upward; and so one went up from the lowest level to the highest through the middle level.
The side rooms surrounding the temple widened at each successive level, because the structure surrounding the temple ascended by stages corresponding to the narrowing of the temple wall as it rose upward. And so a stairway went up from the lowest story to the highest, through the middle one.
