2 Kings 2:9-12

9And so it was, when they had crossed over, that Elijah said to Elisha, “Ask! What may I do for you, before I am taken away from you?” Elisha said, “Please let a double portion of your spirit be upon me.”

10So he said, “You have asked a hard thing. Nevertheless, if you see me when I am taken from you, it shall be so for you; but if not, it shall not be so.”

11Then it happened, as they continued on and talked, that suddenly a chariot of fire appeared with horses of fire, and separated the two of them; and Elijah went up by a whirlwind into heaven.

12And Elisha saw it, and he cried out, “My father, my father, the chariot of Israel and its horsemen!” So he saw him no more. And he took hold of his own clothes and tore them into two pieces.
