Joshua 5:7-9

7And their sons [whom] he raised up in their stead, them Joshua circumcised, for they were uncircumcised, because they had not circumcised them on the way.

8And it came to pass when the whole nation had finished being circumcised, that they abode in their place in the camp, till they were whole.

9And Jehovah said to Joshua, This day have I rolled away the reproach of Egypt from off you. And the name of the place was called Gilgal to this day.
