2 Kings 2:7-12 New Revised Standard Version (NRSV)
7 Fifty men of the company of prophets[a] also went, and stood at some distance from them, as they both were standing by the Jordan. 8 Then Elijah took his mantle and rolled it up, and struck the water; the water was parted to the one side and to the other, until the two of them crossed on dry ground.
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. 12 Elisha kept watching and crying out, “Father, father! The chariots of Israel and its horsemen!” But when he could no longer see him, he grasped his own clothes and tore them in two pieces.
