Joshua 5:1-3

1When all the Amorite kings on the west side of the Jordan and all the Canaanite kings along the seacoast heard how the Lord had dried up the water of the Jordan before the Israelites while they crossed, they lost their courage and could not even breathe for fear of the Israelites.

2At that time the Lord told Joshua, “Make flint knives and circumcise the Israelites once again.”

3So Joshua made flint knives and circumcised the Israelites on the Hill of the Foreskins.
