2 Kings 2:11-12

And as they still went on and talked, behold, chariots of fire and horses of fire separated the two of them. And Elijah went up by a whirlwind into heaven. And Elisha saw it and he cried, “My father, my father! The chariots of Israel and its horsemen!” And he saw him no more. Then he took hold of his own clothes and tore them in two pieces.
