2 Kings 2:9-12

And when they had gone across, Elijah said to Elisha, "Ask what you wish that I may do for you, before I am taken from you." And Elisha said, "I beg you, that twice your spirit may be accomplished in me." And he responded: "You have requested a difficult thing. Nevertheless, if you see me when I am taken from you, you will have what you requested. But if you do not see, it shall not be." And as they continued on, they were conversing while walking. And behold, a fiery chariot with fiery horses divided the two. And Elijah ascended by a whirlwind into heaven. Then Elisha saw it, and he cried out: "My father, my father! The chariot of Israel with its driver!" And he saw him no more. And he took hold of his own garments, and he tore them into two parts.
