II Kings 2:13-18

He also took up the mantle of Elijah that had fallen from him, and went back and stood by the bank of the Jordan. Then he took the mantle of Elijah that had fallen from him, and struck the water, and said, “Where is the LORD God of Elijah?” And when he also had struck the water, it was divided this way and that; and Elisha crossed over. Now when the sons of the prophets who were from Jericho saw him, they said, “The spirit of Elijah rests on Elisha.” And they came to meet him, and bowed to the ground before him. Then they said to him, “Look now, there are fifty strong men with your servants. Please let them go and search for your master, lest perhaps the Spirit of the LORD has taken him up and cast him upon some mountain or into some valley.” And he said, “You shall not send anyone.” But when they urged him till he was ashamed, he said, “Send them!” Therefore they sent fifty men, and they searched for three days but did not find him. And when they came back to him, for he had stayed in Jericho, he said to them, “Did I not say to you, ‘Do not go’?”
