The answer is: 147

Genesis 47:28 - Jacob lived for 147 years, a lifespan that reflects the longevity of patriarchs in early biblical narratives. His story is woven throughout Genesis, showcasing themes of struggle, deception, and redemption, notably in his relationships with Esau and Laban. Interestingly, Jacob's name was changed to Israel, symbolizing his pivotal role in the nation’s ancestry.

Jacob's life, reaching 147 years, certainly places him among some of the most famously long-lived figures in the Bible. It’s fascinating to note that during this period, ancient people were idealized for their extensive lifespans, lending a certain mythical quality to their narratives. For instance, his grandfather, Abraham, lived to 175 years, illustrating a kind of divine favor marked by lengthy years.

Throughout his life, Jacob exemplified resilience. His trickster ways, such as deceiving his brother Esau out of his birthright, demonstrate both cunning and deeply human frailty. The story of these siblings mirrors many familial struggles, inviting readers to reflect on deeper themes of reconciliation and forgiveness. Not to summarily label either brother, one could see aspects of both in a lot of family dynamics—even today!

When Jacob wrestled with the angel and received the name Israel, he not only fought literally but also dealt with tougher spiritual and emotional conflicts. The name "Israel" does mean “he who struggles with God,” which resonates throughout history and equates struggle with divine encounter—a captivating notion encouraging deep introspection.

Moreover, Jacob’s 12 sons became the founders of the tribes of Israel, building a household and forming a nation. This alludes to the way individual experiences—like Jacob's convoluted paths—are often instrumental in shaping broader histories. It invites us to consider how personal trials can interlace with global narratives, revealing an impressive tapestry of human and divine interplay through generations.
