2 Kings 2:4-5 (KJV)

4 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. 5 And the sons of the prophets that were at Jericho came to Elisha, and said unto 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.
