2 Kings 2:4-5

4And Elijah said to him, “Elisha, please 1stay here, for the Lord has sent me to 2Jericho.” But he said, “3As surely as the Lord lives, and as you yourself live, I will not leave you.” So they came to Jericho.

5Then 4the sons of the prophets who were at Jericho approached Elisha and said to him, “5Do you know that the Lord will take away your master from over 6you today?” And he 7answered, “Yes, I know; say nothing about it.”
