2 Kings 2:4-7

4Elijah said to him, “Elisha, please stay here, for the Lord has sent me to Jericho.” But he said, “As the Lord lives and as your soul lives, I will not leave you.” So they came to Jericho.

5The sons of the prophets who were at Jericho approached Elisha and said to him, “Do you know that the Lord will take your master away from you today?” And he answered, “Yes, I know it; be quiet [about it].”

6Elijah said to him, “Please stay here, for the Lord has sent me to the Jordan.” But he said, “As the Lord lives and as your soul lives, I will not leave you.” So the two of them went on.

7Fifty men of the sons of the prophets also went and stood opposite them [to watch] at a distance; and the two of them stood by the Jordan.
