2 Kings 2:5-8

And the sons of the prophets that were at Jericho came near to Elisha, and said unto him, Knowest thou that Jehovah will take away thy master from thy head to-day? And he answered, Yea, I know it; hold ye your peace. And Elijah said unto him, Tarry here, I pray thee; for Jehovah hath sent me to the Jordan. And he said, As Jehovah liveth, and as thy soul liveth, I will not leave thee. And they two went on. And fifty men of the sons of the prophets went, and stood over against them afar off: and they two stood by the Jordan. 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.
