2 Kings 2:9-12

9And it came to pass, when they had gone over, that Elijah said to Elisha, Ask what I shall do for thee, before I am taken away from thee. And Elisha said, I pray thee, let a double portion of thy spirit be upon me. 10And he said, Thou hast asked a hard thing: nevertheless, if thou shalt see me when I am taken from thee, it shall be so to thee; but if not, it shall not be so .1 11And it came to pass, as they still went on, and talked, that, behold, there appeared a chariot of fire, and horses of fire, and separated them; and Elijah went up by a whirlwind into heaven. 12And Elisha saw it, and he cried, My father, my father, the chariot of Israel, and its horsemen. And he saw him no more: and he took hold of his own clothes, and tore them in two pieces.
