2 Kings 6:16-18

He said, “Don’t worry about it—there are more on our side than on their side.” Then Elisha prayed, “O GOD, open his eyes and let him see.” The eyes of the young man were opened and he saw. A wonder! The whole mountainside full of horses and chariots of fire surrounding Elisha! When the Arameans attacked, Elisha prayed to GOD, “Strike these people blind!” And GOD struck them blind, just as Elisha said.
