2 Kings 2:7-9

King James Version

⁷ And fifty men of the sons of the prophets went, and stood to view afar off: and they two stood by Jordan.

⁸ And Elijah took his mantle, and wrapped it together, and smote the waters, and they were divided hither and thither, so that they two went over on dry ground.

⁹ And it came to pass, when they were gone over, that Elijah said unto Elisha, Ask what I shall do for thee, before I be taken away from thee. And Elisha said, I pray thee, let a double portion of thy spirit be upon me.
