So it was, when all the kings of the Amorites who were on the west side of the Jordan, and all the kings of the Canaanites who were by the sea, heard that the Lord had dried up the waters of the Jordan from before the children of Israel until we had crossed over, that their heart melted; and there was no spirit in them any longer because of the children of Israel.
At that time the Lord said to Joshua, "Make flint knives for yourself, and circumcise the sons of Israel again the second time."
So Joshua made flint knives for himself, and circumcised the sons of Israel at the hill of the foreskins.

For all the people who came out had been circumcised, but all the people born in the wilderness, on the way as they came out of Egypt, had not been circumcised.
For the children of Israel walked forty years in the wilderness, till all the people who were men of war, who came out of Egypt, were consumed, because they did not obey the voice of the Lord--to whom the Lord swore that He would not show them the land which the Lord had sworn to their fathers that He would give us, "a land flowing with milk and honey."
References for Joshua 5:6
