Ezekiel 41:5-11

5Afterward he measured the wall of the house, six cubits; and the breadth of every side chamber, four cubits, round the house on every side. 6And the side chambers were three, one over another, and thirty in order; and they entered into the wall which was of the house for the side chambers all around, that they might have hold, but they had not hold in the wall of the house.123 7And there was an enlarging, and a winding about still upward to the side chambers: for the winding about of the house went still upward on all sides of the house: therefore the breadth of the house was still upward, and so went up from the lowest chamber to the highest by the middle chamber .4 8I saw also the height of the house all around: the foundations of the side chambers were a full reed of six great cubits. 9The thickness of the wall, which was for the side chamber on the outside, was five cubits: and that which was left was the place of the side chambers that were within. 10And between the chambers was the width of twenty cubits all around the house on every side. 11And the doors of the side chambers were toward the place that was left, one door toward the north, and another door toward the south: and the breadth of the place that was left was five cubits all around.
