2 Kings 6:15-19

And when the servant of the man of God was risen early, and gone forth, behold, a host with horses and chariots was round about the city. And his servant said unto him, Alas, my master! how shall we do? And he answered, Fear not; for they that are with us are more than they that are with them. And Elisha prayed, and said, Jehovah, I pray thee, open his eyes, that he may see. And Jehovah 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 Jehovah, and said, Smite this people, I pray thee, with blindness. And he smote them with blindness according to the word of Elisha. And Elisha said unto them, This is not the way, neither is this the city: follow me, and I will bring you to the man whom ye seek. And he led them to Samaria.
