Ezekiel 41:6-7

6There were 33 side chambers. There were supports in the wall, which belonged to the House for the side chambers all around, so that they were not supported by the wall of the House.

7The side chambers were wider as they wound about higher and higher. Because the winding about of the House went higher and higher round about the house, therefore the width of the House expanded. One went up from the lowest row to the highest by way of the middle.
