2 Kings 2:9-10

New King James Version

⁹ And so it was, when they had crossed over, that Elijah said to Elisha, “Ask! What may I do for you, before I am taken away from you?”

Elisha said, “Please let a double portion of your spirit be upon me.”

¹⁰ So he said, “You have asked a hard thing. Nevertheless, if you see me when I am taken from you, it shall be so for you; but if not, it shall not be so.”
