48He brought me to the portico of the temple and measured the jambs of the portico; they were five cubits wide on either side. The width of the entrance was fourteen cubits and its projecting walls were three cubits wide on either side. 49The portico was twenty cubits wide, and twelve cubits from front to back. It was reached by a flight of stairs,and there were pillars on each side of the jambs.
