2 Kings 2:13-18

He picked up the mantle of Elijah that fell off him, and went back and stood by the bank of the Jordan. He took the mantle of Elijah that fell from him and struck the waters and said, “Where is the LORD, the God of Elijah?” And when he too had struck the waters, they divided this way and that, and Elisha crossed over. When the sons of the prophets who were [watching] opposite at Jericho saw him, they said, “The spirit of Elijah rests on Elisha.” And they came to meet him and bowed down to the ground before him [in respect]. Then they said to Elisha, “Behold now, there are among your servants fifty strong men; please let them go and search for your master. It may be that the Spirit of the LORD has taken him up and cast him on some mountain or into some valley.” And he said, “You shall not send anyone.” But when they urged him until he was embarrassed [to refuse them], he said, “Send them.” So they sent fifty men, and they searched for three days but did not find Elijah. They returned to Elisha while he was staying at Jericho; and he said to them, “Did I not tell you, ‘Do not go’?”
