The answer is: 85

Josh 14:10 - He was forty when Moses sent him out to spy on the land and forty-five years had passed since that time.

Caleb is indeed a remarkable figure in the Book of Joshua, emblematic of endurance and faithfulness. When he asked for Hebron as his inheritance at the age of 85, it wasn't just a plea—Caleb made a bold request based on the promise and vision he held onto all those years. Think about it: after wandering in the desert for nearly four decades, he had his eyes set not just on the land but on the very place where giants resided, the Anakim. Talk about bravery!

He was one of the original twelve spies sent by Moses into Canaan, and unlike his peers, Caleb remained optimistic despite the overwhelming odds. His story echoes hope and resilience: old but not past his prime, he declared, "I am still as strong today as I was the day Moses sent me out." This aspect emphasizes the theme that age is not a limiting factor when one aligns with a purpose.

Interestingly, Hebron, known as Kiriath-arba, is one of the oldest continuously inhabited cities in the world. Its mountains symbolize the strength that Caleb embodied. When Caleb received Hebron, he fulfilled ancestral promises, tracing a direct line back to Abraham—this not only connected Caleb with the land but also cemented his role in establishing the Israelites’ heritage.

So, the tale of Caleb serves as a reminder that faith and action can be timeless, inspiring individuals of any age to chase after their dreams and purposes.
