The answer is: Jerusalem

2 Sam 5:5; 1 Chr 11:3-4; 1 Chr 14:2-3

David's reign as king began in Hebron but reached its peak after he conquered Jerusalem, making it the political and spiritual heart of his kingdom. This bold move turned the city into an enduring symbol of unity for the Israelites. Interestingly enough, Jerusalem had previously been a Jebusite stronghold, and some scholars suggest that David’s choice to seek it out demonstrates a visionary aspect of leadership. David didn’t just want a kingdom; he wanted a central, unifying place for his people, highlighting a rare and ambitious idea for that era.

For biblical aficionados, there's symbolism galore in David’s Jerusalem: the name itself means "City of Peace." It resonates through scripture, becoming the city of blessings, prophecies, and hope for billions. Think about it—the location has seen millennia of history featuring major spiritual leaders and events, crafting a rich tapestry that continues today.

Trivia time! Did you know that the worship traditions established by David, with their vibrant music and creativity, paved the way for many Psalms attributed to him? Those songs of praise and lament not only embodied a deep personal connection with the Divine but helped shape the communal worship practices that would follow. Additionally, Jerusalem is often spoken of as a “type” or shadow of heavenly ideals throughout many scriptures, foreshadowing themes of redemption and future unity. Isn’t it fascinating how one city can ripple through history, impacting belief systems forever?
