The answer is: Hebron

2 Sam 2:1-3 - Hebron first and then later moved to Jerusalem when he became king over Israel

When Saul and Jonathan met their tragic ends, it marked a significant turning point in Israel's history and for David, who had spent years fleeing from King Saul's jealous fury. David's move to Hebron wasn't just geographical; it was a purposeful claim of leadership and an affirmation of a new era for Israel. Hebron, known for its rich biblical history, served as a fitting backdrop for this dramatic shift. It was the city where Abraham settled and where Sarah was buried, accentuating a deep-rooted tradition and connection to the Israelite ancestors.

David's leadership journey began here as he sought to bring the tribes of Israel together amidst division and rival claims to the throne. His choice of Hebron creates an echo of unity—it was the city where the Davidic line would find its roots as the official capital of Judah, cementing what would later fountain into an influential legacy. The combination of this city’s historical significance and David's royal ambitions paved the way for a unified Israel led under his kingship.

It’s interesting to note that during those early days, David was anointed king over the tribe of Judah while profoundly negotiating the loyalties of the other tribes. This displaying of patience and strategy demonstrates the importance of leadership being earned rather than simply bestowed—a notion that resonates in various heritages of kingship. David's ultimate move to Jerusalem would coincide with more complex kingdom-building, showcasing how identity and governance were intertwined throughout biblical narratives.
