The answer is: 127

Genesis 23:1 - Sarah lived to be 127 years old, making her the only woman in the Bible whose exact age at death is recorded.

Sarah’s remarkable life spanned 127 years, a number steeped in significance within the biblical narrative. As the wife of Abraham and the mother of Isaac, Sarah's relationship with God and her part in His promises played a pivotal role in the foundation of Israel's narrative. Staying strong and faithful quite personal and communal pressures, she holds a unique place in scriptures.

What's interesting is the number 127 itself! In the Hebrew tradition, Numbers often have numerological significance. For 127, when we look at the ways it relates to the covenantal promises God made, it's fascinating to see it reflects themes of fullness and completeness. Sarah waited a long time—90 years—before becoming a mother, which adds to the narrative of hope and patience woven throughout the stories of women in the Bible.

It’s often noted that Sarah also represents the complexities of faith and doubt. Her initial laugh at the notion of bearing a child after such a long wait shows her incredulity, yet she eventually transitions from doubt to belief, offering great significance to the journey many face today. Additionally, her life story can also resonate deeply; she faced challenges with grace, modeled perseverance, and engaged with God intimately.

So while she started as a woman of little faith seen through laughter, she stepped into generational promise, revealing she didn't just age—she evolved beautifully!
