This is why Joshua conducted the circumcision. All the males who had left Egypt, the soldiers, had died in the wilderness on the journey out of Egypt. All the people who had come out of Egypt, of course, had been circumcised, but all those born in the wilderness along the way since leaving Egypt had not been. The fact is that the People of Israel had walked through that wilderness for forty years until the entire nation died out, all the men of military age who had come out of Egypt but had disobeyed the call of GOD. GOD vowed that these would never lay eyes on the land GOD had solemnly promised their ancestors to give us, a land flowing with milk and honey. But their children had replaced them. These are the ones Joshua circumcised. They had never been circumcised; no one had circumcised them along the way.
