This is why Joshua circumcised the men: After the Israelites left Egypt, all the men who were able to serve in the army were circumcised. While in the desert, many of the fighting men did not listen to the Lord. So the Lord promised that they would not see the “land where much food grows.” He promised our ancestors to give us that land, but because of those men, he forced the people to wander in the desert for 40 years. That way all those fighting men would die. So all the fighting men died, and their sons took their place. But none of the boys who were born in the desert on the trip from Egypt had been circumcised. So Joshua circumcised them.
