2 Kings 6:17-20

Then Elisha prayed and said, “LORD, please, open his eyes that he may see.” And the LORD opened the servants eyes and he saw; and behold, the mountain was full of horses and chariots of fire surrounding Elisha. When the Arameans came down to him, Elisha prayed to the LORD and said, “Please strike this people (nation) with blindness.” And God struck them with blindness, in accordance with Elisha’s request. Then Elisha said to the Arameans, “This is not the way, nor is this the city. Follow me and I will lead you to the man whom you are seeking.” And he led them to Samaria. When they had come into Samaria, Elisha said, “LORD, open the eyes of these men, so that they may see.” And the LORD opened their eyes and they saw. Behold, they were in the midst of Samaria.
