II Kings 6:15-20

And when the servant of the man of God arose early and went out, there was an army, surrounding the city with horses and chariots. And his servant said to him, “Alas, my master! What shall we do?” So he answered, “Do not fear, for those who are with us are more than those who are with them.” And Elisha prayed, and said, “LORD, I pray, open his eyes that he may see.” Then the LORD opened the eyes of the young man, and he saw. And behold, the mountain was full of horses and chariots of fire all around Elisha. So when the Syrians came down to him, Elisha prayed to the LORD, and said, “Strike this people, I pray, with blindness.” And He struck them with blindness according to the word of Elisha. Now Elisha said to them, “This is not the way, nor is this the city. Follow me, and I will bring you to the man whom you seek.” But he led them to Samaria. So it was, when they had come to Samaria, that Elisha said, “LORD, open the eyes of these men, that they may see.” And the LORD opened their eyes, and they saw; and there they were, inside Samaria!
