or Mount Zion or Sion\ˈsī-ən, ˈzī-\ or Mount Sion hill E Jerusalem, Israel; originally the stronghold of Jerusalem conquered by David; occupied in ancient times by the Jewish Temple
Easternmost of the two hills of ancient Jerusalem, where David established his royal capital. In the Old Testament, the name Zion frequently refers to Jerusalem as a whole; it is overwhelmingly a poetic and prophetic designation. Mount Zion is the place where Yahweh (God) dwells and is the scene of his messianic salvation. The name came to mean the Jewish homeland, symbolic of Judaism or Jewish national aspirations, and thus was the source of the term Zionism. Though the name is rare in the New Testament, it has been frequently used in Christian literature and hymns as a designation for the heavenly city or for the earthly city of Christian faith and fraternity.
