2 Kings 2:3-11

3And the sons of the prophets that were at Bethel came forth to Elisha, and said to him, Knowest thou that the LORD will take away thy master from thy head to day? And he said, Yea, I know it ; hold ye your peace. 4And Elijah said to him, Elisha, tarry here, I pray thee; for the LORD hath sent me to Jericho. And he said, As the LORD liveth, and as thy soul liveth, I will not leave thee. So they came to Jericho. 5And the sons of the prophets that were at Jericho came to Elisha, and said to him, Knowest thou that the LORD will take away thy master from thy head to day? And he answered, Yea, I know it ; hold ye your peace. 6And Elijah said to him, Tarry here, I pray thee; for the LORD hath sent me to Jordan. And he said, As the LORD liveth, and as thy soul liveth, I will not leave thee. And they two went on. 7And fifty men of the sons of the prophets went, and stood to view afar off: and they two stood by Jordan.1 8And Elijah took his mantle, and wrapped it together, and smote the waters, and they were divided to the one side and to the other, so that they two went over on dry ground.

9And it came to pass, when they had gone over, that Elijah said to Elisha, Ask what I shall do for thee, before I am taken away from thee. And Elisha said, I pray thee, let a double portion of thy spirit be upon me. 10And he said, Thou hast asked a hard thing: nevertheless, if thou shalt see me when I am taken from thee, it shall be so to thee; but if not, it shall not be so .2 11And it came to pass, as they still went on, and talked, that, behold, there appeared a chariot of fire, and horses of fire, and separated them; and Elijah went up by a whirlwind into heaven.
