2 Kings 2:2-3

2And 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.

3And 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.
