Ezekiel 42:8

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

For 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.

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

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

In the thickness of the wall of the court toward the east, before the separate place, and before the building, there were rooms.

The way before them was like the appearance of the rooms which were toward the north. Their length and width were the same. All their exits had the same arrangement and doors.
