2 Kings 2:4-5

4Elijah said to him, “Elisha, stay here; the Lord is sending me to Jericho.” But Elisha said, “As the Lord lives and as you yourself live, I will not leave you.” So they went to Jericho.

5Then the sons of the prophets who were in Jericho came up to Elisha and said, “Do you know that the Lord will take your master away from you today?” He said, “Yes, I know. Be quiet.”
