Zion is the name used as a synonym for Jerusalem. Biblically it was first used in 2 Samuel 5:7. Theologians refer it to a specific mountain near Jerusalem: Mount Zion. It is both a symbolic, metaphoric and actual location as the City of David, later becoming a metonym for Solomon’s Temple. Its eschatological focus is the future promised City of God in the Millennium and the Eternal State. The New Jereusalm, the captial of the Messianic Kingdom.
