Caleb had been promised a piece of property 45 years earlier. Since that promise, he spent 40 years wandering in the wilderness with a bunch of dissatisfied, unfaithful, whining people. Then under Joshua’s leadership, Caleb spent five years fighting as a soldier against the Canaanite kingdoms. Even after 45 years, he still held onto God’s promise. “I remember God’s promise to me; now give me this hill country!” He never let go of that promise–that’s what the Bible calls persistence.
