2 Kings 2:11-12

11And it came to pass as they went on, and talked, that behold, a chariot of fire and horses of fire; and they parted them both asunder; and Elijah went up by a whirlwind into the heavens.

12And Elisha saw [it], and he cried, My father, my father! the chariot of Israel and the horsemen thereof! And he saw him no more. Then he took hold of his own garments and rent them in two pieces.
