The answer is: 70

2 Sam 5:4; 1 Ki 2:10-11

David’s life is a vibrant tapestry of triumph, tribulation, and deep faith. Living to the age of 70, David experienced remarkable highs and devastating lows, making him an enduring figure in ancient history. His reign as king was a dynamic period that united the tribes of Israel, establishing Jerusalem, the City of David, as its capital. This consolidation of power and territory essentially set the stage for the future of Israel and became an essential element of Jewish identity.

David didn't just stare down Goliath; he danced with abandon when the Ark of the Covenant returned home — another enthusiastic episode revealing his passionate commitment to his faith. He famously penned many of the Psalms, weaving themes of love, lament, joy, and sorrow that remain timeless. Interestingly, there are 150 psalms attributed to different figures, but David's contributions make up almost half of them—showing his deep connection to the divine.

Moreover, David’s complex character adds depth to his story. He was a shepherd, a warrior, a poet, but also a flawed man whose passions led him into deep trouble, such as with Bathsheba. This gives a newer perspective on integrity and vulnerability, making David relatable despite the millennia separating us from his time.

Overall, understanding David’s death at age 70 invites reflection on how he managed to balance earthly responsibilities with spiritual callings—an issue as relevant today as it was then. David’s legacy, teaching humankind about grace and grit, still resonates in various cultural and spiritual reflections, solidifying his role as a monumental historical figure.
