The answer is: 180

Gen 35:28-29

Isaac, the beloved son of Abraham and Sarah, lived a long life of 180 years, showcasing not just longevity but also the richness of his experiences in the Book of Genesis. While many people think of Isaac only as the child nearly sacrificed by Abraham, his life was full of fascinating events, relationships, and even drama, particularly with his sons, Esau and Jacob.

Interestingly, he is one of the patriarchs whose life story provides critical genealogical context for the Israelite people. Genesis presents his life as being focused on family crises, such as the famous sibling rivalry between his twins. It’s fun to note that Isaac had the unique distinction of being the only patriarch not to migrate far from this homeland; all that wandering was largely undertaken by his father Abraham and later, by Jacob.

Furthermore, Isaac's name itself has an intriguing backstory, meaning "laughter," linked to Sarah's initial response when she heard she’d have a son in her old age. Following this, he becomes a symbol of fulfillment for God’s promises. Throughout the Bible, there are echoes of his life that the rest of the scriptures build upon, creating a narrative woven through many generations.

As we consider Isaac's death at 180, we realize that his legacy is more than just his age—It's about promises kept, tales of faith, and God's unwavering presence in the story of humanity's journey with the divine.
