Ezekiel 41:9-11

New International Version

⁹ The outer wall of the side rooms was five cubits thick. The open area between the side rooms of the temple ¹⁰ and the priests’ rooms was twenty cubits wide all around the temple. ¹¹ There were entrances to the side rooms from the open area, one on the north and another on the south; and the base adjoining the open area was five cubits wide all around.
