Joshua 5:3-5

New Revised Standard Version Catholic Edition

³ So Joshua made flint knives, and circumcised the Israelites at Gibeath-haaraloth.^{[a] 4} This is the reason why Joshua circumcised them: all the males of the people who came out of Egypt, all the warriors, had died during the journey through the wilderness after they had come out of Egypt. ⁵ Although all the people who came out had been circumcised, yet all the people born on the journey through the wilderness after they had come out of Egypt had not been circumcised.
