Joshua 5:3-5

Revised Standard Version Catholic Edition

³ So Joshua made flint knives, and circumcised the people of Israel at Gib′eath-ha-ar′aloth.^{[a] 4} And this is the reason why Joshua circumcised them: all the males of the people who came out of Egypt, all the men of war, had died on the way in the wilderness after they had come out of Egypt. ⁵ Though all the people who came out had been circumcised, yet all the people that were born on the way in the wilderness after they had come out of Egypt had not been circumcised.
