What does the Bible say about the significance of Jerusalem in David's reign?

In 2 Samuel 5, Jerusalem emerges as a pivotal location, symbolizing the establishment of God's kingdom under King David. David's reign in Jerusalem illustrates a type of Christ's sovereign kingship, fulfilling the prophetic role as the King of Kings. Just as David conquered Jerusalem, Christ conquers sin and death, establishing His spiritual kingdom among His people. This parallels the New Jerusalem, which is ultimately redeemed by Christ's sacrifice, reflecting the heavenly city that God prepares for His redeemed.
