2 Kings 2:9-12

When they had gone over, Elijah said to Elisha, “Ask what I shall do for you, before I am taken from you.” Elisha said, “Please let a double portion of your spirit be on me.” He said, “You have asked a hard thing. If you see me when I am taken from you, it will be so for you; but if not, it will not be so.” As they continued on and talked, behold, a chariot of fire and horses of fire separated them; and Elijah went up by a whirlwind into heaven. Elisha saw it, and he cried, “My father, my father, the chariots of Israel and its horsemen!” He saw him no more. Then he took hold of his own clothes and tore them in two pieces.
