Ezekiel 41:5-7

New International Version - UK

⁵ Then he measured the wall of the temple; it was six cubits thick, and each side room round the temple was four cubits^[a] wide. ⁶ The side rooms were on three levels, one above another, thirty on each level. There were ledges all round the wall of the temple to serve as supports for the side rooms, so that the supports were not inserted into the wall of the temple. ⁷ The side rooms all round the temple were wider at each successive level. The structure surrounding the temple was built in ascending stages, so that the rooms widened as one went upwards. A stairway went up from the lowest floor to the top floor through the middle floor.
