Joshua 5:1-3

1So 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.

2At that time the Lord said to Joshua, “Make flint knives for yourself, and circumcise the sons of Israel again the second time.”

3So Joshua made flint knives for himself, and circumcised the sons of Israel at the hill of the foreskins.
