2 Kings 6:14-17

So one night the king of Aram sent a great army with many chariots and horses to surround the city. When the servant of the man of God got up early the next morning and went outside, there were troops, horses, and chariots everywhere. “Oh, sir, what will we do now?” the young man cried to Elisha. “Don’t be afraid!” Elisha told him. “For there are more on our side than on theirs!” Then Elisha prayed, “O LORD, open his eyes and let him see!” The LORD opened the young man’s eyes, and when he looked up, he saw that the hillside around Elisha was filled with horses and chariots of fire.
