2 Kings 2:8-10

Amplified Bible

⁸ And Elijah took his mantle (coat) and rolled it up and struck the waters, and they were divided this way and that, so that the two of them crossed over on dry ground.

⁹ And when they had crossed over, Elijah said to Elisha, “Ask what I shall do for you before I am taken from you.” And Elisha said, “Please let a double ^[a]portion of your spirit be upon me.” ¹⁰ He said, “You have asked for a difficult thing. However, if you see me when I am taken from you, it shall be so for you; but if not, it shall not be so.”
