Joshua 5:1-3

Amplified Bible, Classic Edition

5 When all the kings of the Amorites who were beyond the Jordan to the west and all the kings of the Canaanites who were by the sea heard that the Lord had dried up the waters of the Jordan before the Israelites until we had crossed over, their hearts melted and there was no spirit in them any more because of the Israelites.

² At that time the Lord said to Joshua, Make knives of flint and circumcise the [new generation of] Israelites as before.

³ So Joshua made knives of flint and circumcised the sons of Israel at Gibeath-haaraloth.
