Ezekiel 41:4-6

New International Version - UK

⁴ And he measured the length of the inner sanctuary; it was twenty cubits, and its width was twenty cubits across the end of the main hall. He said to me, ‘This is the Most Holy Place.’

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.
