2 Kings 6:17-20

Then Elisha prayed, “LORD, open my servant’s eyes, and let him see.” The LORD opened the eyes of the young man, and he saw that the mountain was full of horses and chariots of fire all around Elisha. As the enemy came down toward Elisha, he prayed to the LORD, “Make these people blind.” So he made the Aramean army blind, as Elisha had asked. Elisha said to them, “This is not the right road or the right city. Follow me and I’ll take you to the man you are looking for.” Then Elisha led them to Samaria. After they entered Samaria, Elisha said, “LORD, open these men’s eyes so they can see.” So the LORD opened their eyes, and the Aramean army saw that they were inside the city of Samaria!
