“And Elisha prayed, and said, Lord, I pray thee, open his eyes, that he may see. And the Lord opened the eyes of the young man; and he saw: and, behold, the mountain was full of horses and chariots of fire round about Elisha. And when they came down to him, Elisha prayed unto the Lord, and said, Smite this people, I pray thee, with blindness. And he smote them with blindness according to the word of Elisha.”
2 Kings 6:17-18 KJV
