'Circumcision' in the Bible

At that time the Lord said to Joshua, Make yourself stone knives and give the children of Israel circumcision a second time.

So Joshua made stone knives and gave the children of Israel circumcision at Gibeath-ha-araloth.

All the people who came out had undergone circumcision; but all the people whose birth had taken place in the waste land on their journey from Egypt had not.

And their children, who came up in their place, now underwent circumcision by the hands of Joshua, not having had it before: for there had been no circumcision on the journey.

So when all the nation had undergone circumcision, they kept in their tents till they were well again.
