2 Kings 2:16-18

16Then 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.”

17But 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.

18They returned to Elisha while he was staying at Jericho; and he said to them, “Did I not tell you, ‘Do not go’?”
