The conquest of Jerusalem and its establishment as the kingdom’s capital probably took place after the final victory over the Philistines, possibly following other foreign campaigns. The author strongly highlights the theological connection between David’s selection as king and Jerusalem’s designation as the capital. From that point on, they will form a strong unity as a new act of the Lord and the beginning of a new historical era. Therefore, it makes sense to present these two events together at the start of the narrative. David chooses to establish a new capital—a city without tribal ties, well located, and of great strategic importance: Jerusalem, a symbol of Canaanite resilience and resistance.
David’s decision demonstrates boldness and foresight. It is bold because it involves a risky challenge, and a failed attack could damage the new king’s reputation. Foresight, as history shows, makes Jerusalem spiritually important for Israel and later for the Jews, far beyond its physical, strategic, and urban value. By examining the facts, David recognizes his divine destiny: he is a king by God’s grace, serving the people not as a privilege but as a responsibility. Since the people belong to the Lord, David acts as a vassal and mediator serving them. His role as a vassal in Gath and likely in Hebron reflects the new historical context. Verses 13-16 indicate the future heir: he will be one of the sons born in Jerusalem, not from Hebron.
