Though the Book of Joshua doles out the praise to Joshua most of the time, Caleb is another guy worth writing home about.
Caleb, along with Joshua, was one of the original twelve spies sent into the Promised Land to scout the area. While everyone else was too afraid to conquer Canaan, Caleb and Joshua announced that there would be no trouble for the Israelites. All of this goes down in Numbers 13-14.
Flash forward to the Book of Joshua. Caleb is 85 years old now. As a reward for his years of faithfulness to God, he is granted the land of Hebron as his inheritance (14:6-15). Pretty sweet deal if you ask us. Become a spy, get rewarded with some land. He's basically a Jewish James Bond.
