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 remarkable lifespan of 147 years not only highlights his longevity but also showcases the thematic parallels between his age and the powerful narratives surrounding the early Hebrew patriarchs. Living so long was not unusual for this era, as mentioned in accounts of figures like Methuselah, who is said to have lived 969 years. These extended lifespans cultivate a portrayal of a time when people were closer to God and life was less precarious than as we know it today.

Imagine the rich life Jacob experienced over nearly a century and a half! His infamous wrestling match with a divine figure left him with a new name—Israel—which means “he who struggles with God.” This pivotal encounter through a night-long struggle beautifully symbolizes the complexity of faith, including doubts and uncertainties. Struggling with his brother Esau for his birthright and later contending with his shifty uncle Laban creates a tapestry of familial rivalry laced with determination and often deception.

Jacob's legacy spans the backdrop of the Israelite people, directly influencing their fate. Not to forget, he fathers twelve sons, who become the tribes of Israel, an important aspect of the heritage of the Israelite nation. Additionally, Jacob's life resonates with us today and inspires introspection on central themes: familial bonds, life’s capriciousness, and the quest for meaningful connections that define each generation’s identity more than their years alone. Each age in his life saw transformation, much like the ages we navigate, holding wisdom shaped by our experiences and struggles.
