2 Kings 6:15-20

When the servant of the man of God got up early and went out, he discovered an army with horses and chariots surrounding the city. So he asked Elisha, “Oh, my master, what are we to do?” Elisha said, “Don’t be afraid, for those who are with us outnumber those who are with them.” Then Elisha prayed, “LORD, please open his eyes and let him see.” So the LORD opened the servant’s eyes, and he saw that the mountain was covered with horses and chariots of fire all around Elisha. When the Arameans came against him, Elisha prayed to the LORD, “Please strike this nation with blindness.” So he struck them with blindness, according to Elisha’s word. Then Elisha said to them, “This is not the way, and this is not the city. Follow me, and I will take you to the man you’re looking for.” And he led them to Samaria. When they entered Samaria, Elisha said, “LORD, open these men’s eyes and let them see.” So the LORD opened their eyes, and they saw that they were in the middle of Samaria.
