Ezekiel 41:8

6 And the side chambers three, one over another, and thirty in order; and they entered into the wall which of the house for the side chambers round about, that they might have hold, but they had not hold in the wall of the house.

7 And an enlarging, and a winding about still upward to the side chambers: for the winding about of the house went still upward round about the house: therefore the breadth of the house upward, and so increased the lowest to the highest by the midst.

8 I saw also the height of the house round about: the foundations of the side chambers a full reed of six great cubits.

9 The thickness of the wall, which for the side chamber without, five cubits: and which left the place of the side chambers that within.

10 And between the chambers the wideness of twenty cubits round about the house on every side.
