Gabriel Barkay: St. Andrew's Church, Jerusalem: In August-September 1975 a salvage excavation was carried out on the hill near St. Andrew's Church in Jerusalem, between the road leading up to the church and the road descending to the Valley of Hinnom. This is an important strategic point on the ancient watershed road through the Judean hills, where two natural roads meet, one from the Valley of Hinnom in the west and one from the Valley of Rephaim in the east... A large block of stone 2.80 m. [9.2 feet] long, belonging to a threshold originally some 5 m. [16.5 feet] wide, was visible on the surface. Excavation revealed that the threshold stone is in situ, and that it is part of a monumental architectural complex. ==Scrolls==
