Joshua 5:7 in the King James Version
And their children, whom he raised up in their stead, them Joshua circumcised: for they were uncircumcised, because they had not circumcised them by the way.
Context
6 For the children of Israel walked forty years in the wilderness until all the nation, even the men of war who came out of Egypt, were consumed, because they didn’t listen to the LORD’s voice. The LORD swore to them that he wouldn’t let them see the land which the LORD swore to their fathers that he would give us, a land flowing with milk and honey.
7 Their children, whom he raised up in their place, were circumcised by Joshua, for they were uncircumcised, because they had not circumcised them on the way.
8 When they were done circumcising the whole nation, they stayed in their places in the camp until they were healed.
