徒 Acts 19:13-17
13 那时，有几个赶鬼的犹太人，周游各处，擅自用主耶稣的名，向身上有邪灵的人说：“我奉保罗所传的耶稣的名，命令你们出来。”14 有一个犹太人士基瓦，是祭司长，他的七个儿子都作这事。15 邪灵回答他们：“耶稣我认识，保罗我也知道；你们是谁？”16 邪灵所附的那人就扑到他们身上，制伏了两人，胜过了他们，使他们赤着身带着伤，从那房子逃了出来。17 所有住在以弗所的犹太人和希腊人，都知道这件事；大家都惧怕，尊主耶稣的名为大。
13 Some Jews who went around driving out evil spirits tried to invoke the name of the Lord Jesus over those who were demon-possessed. They would say, “In the name of the Jesus whom Paul preaches, I command you to come out.” 14 Seven sons of Sceva, a Jewish chief priest, were doing this. 15 One day the evil spirit answered them, “Jesus I know, and Paul I know about, but who are you?” 16 Then the man who had the evil spirit jumped on them and overpowered them all. He gave them such a beating that they ran out of the house naked and bleeding. 17 When this became known to the Jews and Greeks living in Ephesus, they were all seized with fear, and the name of the Lord Jesus was held in high honour.
Here it may be seen more clearly that Paul’s apostleship was confirmed by the miracles Luke has just mentioned, he now teaches that when some people falsely claimed the name of Christ, this abuse was sharply punished. From this we learn that Paul performed these miracles only in order that everyone should know that he was faithfully preaching Christ as the power of God, for the Lord did not allow them to be separate from the pure doctrine of the Gospel.
