As yet I am as strong this day as I as in the day that Moses sent me: as my strength was then, even so is my strength now, for war, and to go out and to come in.
The references to Caleb’s age enable us to determine the length of the conquest of Canaan. Caleb had received the promise of a portion in the land at Kadesh Barnea 38 years before the Israelites crossed the Jordan and entered Canaan (Numbers 14:24). Caleb was 40 years old then (Joshua 14:7). He was now 85 (Joshua 14:10). Forty-five years had elapsed, and Caleb had spent 38 of them in the wilderness. Therefore the conquest must have taken the remaining seven years.
