Sunny; height, one of the eminences on which Jerusalem was built. It was surrounded on all sides, except the north, by deep valleys, that of the Tyropoeon (q.v.) separating it from Moriah (q.v.), which it surpasses in height by 105 feet. It was the south-eastern hill of Jerusalem.
In the New Testament (see SION) it is used sometimes to denote the Church of God (Heb. 12:22), and sometimes the heavenly city (Rev. 14:1).
