2 Kings 6:16-18

“Don’t be afraid!” Elisha told him. “For there are more on our side than on theirs!” Then Elisha prayed, “O LORD, open his eyes and let him see!” The LORD opened the young man’s eyes, and when he looked up, he saw that the hillside around Elisha was filled with horses and chariots of fire. As the Aramean army advanced toward him, Elisha prayed, “O LORD, please make them blind.” So the LORD struck them with blindness as Elisha had asked.
