2 Kings 2:16-18

16and said to him, Behold now, there are with thy servants fifty valiant men; let them go, we pray thee, and seek thy master, lest perhaps the Spirit of Jehovah have taken him up, and cast him upon some mountain, or into some ravine. And he said, Ye shall not send.

17And they pressed him till he was ashamed, and he said, Send. They sent therefore fifty men, and they sought three days, but did not find him.

18And they came again to him (now he was staying at Jericho); and he said to them, Did I not say to you, Go not?
