2 Kings 2:5-7

New King James Version

⁵ Now the sons of the prophets who were at Jericho came to Elisha and said to him, “Do you know that the Lord will take away your master from over you today?”

So he answered, “Yes, I know; keep silent!”

⁶ Then Elijah said to him, “Stay here, please, for the Lord has sent me on 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. ⁷ And fifty men of the sons of the prophets went and stood facing them at a distance, while the two of them stood by the Jordan.
