The answer is: 180

Gen 35:28-29

When talking about Isaac, the son of Abraham and Sarah, we often picture him as a mere boy during the near-sacrifice story (Genesis 22), but his life is rich with experiences that lead up to his death at the ripe age of 180. Just imagine knowing your family history – from the promise made to Abraham to the significant events in Rebekah’s life. Isaac wasn’t just a character in a tale; he played a pivotal role in establishing the covenant that became central to Judaism.

Isn’t it fascinating that Isaac lived a long life? This makes him one of the oldest patriarchs in the Bible! Interestingly, while Abraham lived to be 175 years, the longevity does raise a few eyebrows regarding ancient practices, health, or perhaps even divine favor. There's a tradition among some scholars that suggests such lengthy lifespans signify a time when humanity was closer to its origins, infused with vitality before generations diverged.

Isaac’s death at 180 slots him into a lineage steeped with intrigue, notably being the father of Jacob (later Israel) and Esau. They symbolize two nations, weaving a story that goes on to shape the world’s religious tapestry today. Thus Isaac stands not merely as a name but a bridge, leading readers through numerous historical textures that blanket biblical accounts. That’s legacy work at its finest!
