¹⁰ And between it and the wall chambers was a width of twenty cubits all around the temple on every side. ¹¹ The doors of the side chambers opened on the terrace, one door toward the north and another toward the south; and the width of the terrace was five cubits all around.

¹² The building that faced the separating courtyard at its western end was seventy cubits wide; the wall of the building was five cubits thick all around, and its length ninety cubits.
