Melaḵim Bĕt (2 Kings) 6:14-17

And he sent horses and chariots and a great army there, and they came by night and surrounded the city. And the servant of the man of Elohim rose early and went out, and saw an army, surrounding the city with horses and chariots. And his servant said to him, “Oh, my master! What do we do?” And he answered, “Do not fear, for those who are with us are more than those who are with them.” And Elisha prayed, and said, “יהוה, I pray, open his eyes and let him see.” And יהוה opened the eyes of the young man, and he looked and saw the mountain covered with horses and chariots of fire all around Elisha.
