2 Kings 2:9-11

9 When they had crossed, Elijah said to Elisha, "Tell me what I may do for you, before I am taken from you." Elisha said, "Please let me inherit a double share of your spirit."
10 He responded, "You have asked a hard thing; yet, if you see me as I am being taken from you, it will be granted you; if not, it will not."
11 As they continued walking and talking, a chariot of fire and horses of fire separated the two of them, and Elijah ascended in a whirlwind into heaven.
