Don't be afaid," the prophet answered. "Those who are with us are more than those are with them,"


And Elisha prayed, "O Lord, open his eyes so he may see." 
The the Lord opened the servants eyes, and he looked and he saw

As the enemy came down toward him , Elisha prayed to the Lord. 


"Strike these people with blindness," So he struck them with blindness as Elisha had asked.
