2 Kings 6:18-19

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. 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. But he led them to Samaria.
