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 a fascinating character in the Book of Joshua, not just for his role as one of the original twelve spies sent to scout the Promised Land, but also for his immensely admirable attitude toward life and God’s promises. At 85 years old, he boldly approaches Joshua, asking for the hill country of Hebron, a mountainous region filled with impressive challenges. Isn’t it quite inspiring that he felt ready to take on fierce giants even at that age? This speaks volumes about both Caleb’s unwavering faith and his indomitable spirit.

Caleb holds a special place in biblical storytelling as one of the only spies to return with an optimistic report. He surrounded himself with positive energy, citing God's support instead of focusing on fear, which is a remarkable lesson on maintaining courage in the face of adversity. His story echoes the idea of divine rewards for steadfast faith—he had a heart set on pursuing what was promised to him.

Fun trivia: Hebron is mentioned numerous times in biblical texts and is responsible for some significant events, like being close to Abraham’s burial site. Interestingly, it’s also called “the city of Abraham” and holds historical weight with a strong connection to lineage in scriptures.

Caleb's age not only signifies endurance but shows a lifestyle of agile faithfulness that asks us to ponder—what might we pursue or achieve today with relentless faith?
