Ezekiel 41:5-7

Revised Geneva Translation

⁵ Afterward, he measured the wall of the House (six cubits) and the width of every chamber (four cubits) all around the House, on every side.

⁶ And the chambers were in three stories, one above the other, thirty chambers in each story. And they entered into the walls made for the chambers, which was all around the House, so that the posts might be fastened to them and not be fastened to the wall of the House.

⁷ And it was large, and went around, mounting upward to the chambers. For the stairs of the House mounted upward, all around the House. Therefore, the House was larger further up. So, they went up from the lowest chamber to the highest by way of the middle.
