Psalm 87:2–3 says, “The Lord loves the gates of Zion / more than all the other dwellings of Jacob. / Glorious things are said of you, / city of God.” According to this verse, Zion is synonymous with city of God, and it is a place that God loves. Zion is Jerusalem. Mount Zion is the high hill on which David built a citadel. It is on the southeast side of the city.
