2 Kings 2:1-4

And it came to pass, when the LORD would take up Elijah into heaven by a whirlwind, that Elijah went with Elisha from Gilgal.

And Elijah said unto Elisha, Tarry here, I pray thee; for the LORD hath sent me to Beth-el. And Elisha said unto him, As the LORD liveth, and as thy soul liveth, I will not leave thee. So they went down to Beth-el.

And the sons of the prophets that were at Beth-el came forth to Elisha, and said unto 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.

And Elijah said unto 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.
