2 Kings 6:15-17
New International Version
15 When the servant of the man of God got up and went out early the next morning, an army with horses and chariots had surrounded the city. “Oh no, my lord! What shall we do?” the servant asked.
17 And Elisha prayed, “Open his eyes, Lord, so that he may see.” Then the Lord opened the servant’s eyes, and he looked and saw the hills full of horses and chariots(C) of fire all around Elisha.
