2 Kings 6:15-17

Now when the attendant of the man of God had risen early and gone out, behold, an army with horses and chariots was circling the city. 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.” Then Elisha prayed and said, “O LORD, I pray, open his eyes that he may see.” And the LORD opened the servant’s eyes and he saw; and behold, the mountain was full of horses and chariots of fire all around Elisha.
