2 Kings 6:17-18

17 Then Elisha prayed and said, “O  Lord, please a open his eyes that he may see.” So the  Lord opened the eyes of the young man, and he saw, and behold, the mountain was full of b horses and chariots of fire all around Elisha. 18 And when the Syrians came down against him, Elisha prayed to the  Lord and said, “Please strike this people with blindness.” c So he struck them with blindness in accordance with the prayer of Elisha.
