2 Kings 2:8-12 ESV
Then Elijah took his cloak and rolled it up and struck the water, and the water was parted to the one side and to the other, till the two of them could go over on dry ground.
When they had crossed, Elijah said to Elisha, “Ask what I shall do for you, before I am taken from you.” And Elisha said, “Please let there be a double portion of your spirit on me.” And he said, “You have asked a hard thing; yet, if you see me as I am being taken from you, it shall be so for you, but if you do not see me, it shall not be so.” And as they still went on and talked, behold, chariots of fire and horses of fire separated the two of them. And Elijah went up by a whirlwind into heaven. And Elisha saw it and he cried, “My father, my father! The chariots of Israel and its horsemen!” And he saw him no more.
Then he took hold of his own clothes and tore them in two pieces.
