Joshua said to them, "Do not be afraid, nor be dismayed. Be strong and of good courage, for the LORD will do this to all your enemies against whom you fight."

The LORD said to Joshua, "Do not be afraid because of them; for tomorrow at this time, I will deliver them up all slain before Israel. You shall hamstring their horses and burn their chariots with fire."
