Ezekiel 42:7

5Now the upper rooms were shorter; for the galleries took away from these more than from the lower and the middle in the building.

6For they were in three stories, and they didn’t have pillars as the pillars of the courts. Therefore the uppermost was set back more than the lowest and the middle from the ground.

7The wall that was outside by the side of the rooms, toward the outer court before the rooms, was fifty cubits long.

8For the length of the rooms that were in the outer court was fifty cubits. Behold, those facing the temple were one hundred cubits.

9From under these rooms was the entry on the east side, as one goes into them from the outer court.
