The answer is: 70

(2 Samuel 5:4) + (2 Samuel 5:4) = (30) + (40) = 70

David is a hallmark character in the Bible, not just for his captivating rise from shepherd boy to king, but also for his total years of influence and leadership over Israel. When David became king, he was 30 years old—a fact often overshadowed by the giant-slaying tales from his youth. This transition into monarchy, laid out in 2 Samuel 5:4, marked the beginning of a significant phase in Israel’s history.

His 40-year reign is equally vital, as it encapsulates some defining moments for ancient Israel: the establishment of Jerusalem as the capital and the bringing of the Ark of the Covenant there, symbolizing God’s presence among the people. David did a tremendous job uniting the tribes—something that translates into an impressive narrative of leadership that aimed toward establishing a lasting legacy. Fun fact—Jerusalem was previously a Jebusite fortress!

This number crunch (70 years) isn’t just about math; it’s about understanding the depth of David's life experience. Congregational societies have revered him for his poetic prowess, too, as many of his psalms echo themes of struggle, hope, and yearning. His story highlights immense flaws—like his moral failings with Bathsheba—but God’s unwavering commitment to David remains a central theme throughout. David's life also introduces the tapestry of human experience: from triumphs to shortcomings, illustrating that strength is often found through resilience and learning.
