2 Kings 2:13-18

And he took up the cloak of Elijah that had fallen from him and went back and stood on the bank of the Jordan. Then he took the cloak of Elijah that had fallen from him and struck the water, saying, “Where is the LORD, the God of Elijah?” And when he had struck the water, the water was parted to the one side and to the other, and Elisha went over. Now when the sons of the prophets who were at Jericho saw him opposite them, they said, “The spirit of Elijah rests on Elisha.” And they came to meet him and bowed to the ground before him. And they said to him, “Behold now, there are with your servants fifty strong men. Please let them go and seek your master. It may be that the Spirit of the LORD has caught him up and cast him upon some mountain or into some valley.” And he said, “You shall not send.” But when they urged him till he was ashamed, he said, “Send.” They sent therefore fifty men. And for three days they sought him but did not find him. And they came back to him while he was staying at Jericho, and he said to them, “Did I not say to you, ‘Do not go’?”
