Yahweh said to Joshua, Don't be afraid because of them; for tomorrow at this time will I deliver them up all slain before Israel: you shall hamstring their horses, and burn their chariots with fire.
Hamstringing involved cutting the hamstring muscle of the horses’ legs. Hamstringing the horses and burning the chariots (Joshua 11:6; Joshua 11:9) had two effects. The enemy could not use them again, and the Israelites could not use them or trust in them.
