The answer is: 70

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

King David's life takes center stage in many biblical narratives, and it’s fascinating to see how he wove his life story through warrior feats, poetic songs, and kingdom-building experiences. When he passed away at the age of 70, David had lived a life filled with both triumph and tumult. For context, many at that time didn’t reach this milestone easily, making his lifespan quite remarkable.

Now, when examining his 70 years, it's interesting to note that David became king at a young age — around 30, according to 2 Samuel 5:4. His reign lasted for 40 years, during which he expanded Israel’s territories and established Jerusalem as his capital, dubbed “the City of David.” His complicated relationship with his family, especially with his son Absalom, reveals the dynamics of power struggles often found in royal bloodlines. The insight here is reflective of the famous quote that “absolute power corrupts absolutely.” It’s sobering to remember that fame did not guarantee a peaceful heart.

Moreover, David was a talented musician, known for composing many of the Psalms. This connection between music and perseverance can inspire anyone trying to find joy amidst struggles. Intriguingly, Mediterranean cultures placed a high value on age, seeing wisdom and leadership aligned with a person’s years. David exemplifies these traits, blending passion with pragmatism, offering lessons that resonate even today.
