The answer is: 110

Judges 2:8

Joshua's age at death, 110 years, offers intriguing insight into the biblical narrative and historical context. Symbolically, numbers hold significant weight in Scripture, and the number 110 is often associated with divine perfection, being ten decades-old—one complete cycle of an earthly life.

In the broader narrative of Israel's history, Joshua represents a significant bridge between the leadership of Moses and the turbulent times when judges ruled. Under Joshua’s leadership, the Israelites entered the Promised Land and began to settle, marking the fulfillment of God's promise. Interestingly, his life events echo the ancestor Abraham, who entered a new promise at a venerable age too. Both figures illustrate courage and commitment to divine guidance, imparting lessons of perseverance.

When Joshua dies, it signifies a turning point. The next chapters highlight Israel's cyclical pattern of fidelity followed by rebellion—the recurring "might makes right cycles." By reflecting on Joshua's faith and the chapters that dissolve into the chaos of the judges' reign, readers witness the consequences of straying from unity and adherence to ideals, parallel to shifts in personal lives today.

Finally, the tradition of long, prosperous life speaks to the value placed on wisdom and capability bestowed over many years in ancient cultures. Joshua’s legacy would stir discussion among future leaders, reminding them that patience and divine alliance carried them thus far. Exploring Joshua's contributions allows modern readers to glean ways of grounding their paths amid the lows and highs of life's journey.
