Ezekiel 41:5-11

5And he measured the wall of the house, six cubits; and the breadth of the side-chambers, four cubits, round about the house on every side.

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

7And for the side-chambers there was an enlarging, and it went round about [the house] increasing upward; for the surrounding of the house increased upward round about the house; therefore the house had width upward, and so ascended [from] the lower [story] to the upper, by the middle one.

8And I saw that the house had an elevation round about: the foundations of the side-chambers, a full reed, six cubits to the joint.

9The thickness of the wall, which was for the side-chambers without, was five cubits, as also what was left free along the building of the side-chambers that pertained to the house.

10And between the cells [and the house] was a width of twenty cubits round about the house on every side.

11And the entry of the side-chambers was toward what was left free, one entry toward the north, and one entry toward the south; and the width of the space left free was five cubits round about.
