Ezekiel 41:9-11

Amplified Bible

⁹ The thickness of the outer wall of the side chambers was five cubits. But the free space between the side chambers belonging to the temple ¹⁰ and the outer chambers was a width of twenty cubits all around the temple on every side. ¹¹ The doorways of the side chambers toward the free space were one doorway toward the north and another doorway toward the south; and the width of the free space was five cubits all around.
