2 Kings 2:13-18 (NRSV)
13 He picked up the mantle of Elijah that had fallen from him, and went back and stood on the bank of the Jordan. 14 He took the mantle of Elijah that had fallen from him, and struck the water, saying, “Where is the LORD, the God of Elijah?” When he had struck the water, the water was parted to the one side and to the other, and Elisha went over.
15 When the company of prophets who were at Jericho saw him at a distance, they declared, “The spirit of Elijah rests on Elisha.” They came to meet him and bowed to the ground before him. 16 They said to him, “See now, we have fifty strong men among your servants; please let them go and seek your master; it may be that the spirit of the LORD has caught him up and thrown him down on some mountain or into some valley.” He responded, “No, do not send them.” 17 But when they urged him until he was ashamed, he said, “Send them.” So they sent fifty men who searched for three days but did not find him. 18 When they came back to him (he had remained at Jericho), he said to them, “Did I not say to you, Do not go?”
