Acts 19:6-16

6 and when Paul laid his hands upon them, the Holy Spirit came on them, and they began to speak in tongues and to prophesy.
7 They numbered in all about twelve men.
8 Afterwards he went into the synagogue. There for three months he continued to preach fearlessly, explaining in words which carried conviction the truths which concern the Kingdom of God.
9 But some grew obstinate in unbelief and spoke evil of the new faith before all the congregation. So Paul left them, and, taking with him those who were disciples, held discussions daily in Tyrannus's lecture-hall.
10 This went on for two years, so that all the inhabitants of the province of Asia, Jews as well as Greeks, heard the Lord's Message.
11 God also brought about extraordinary miracles through Paul's instrumentality.
12 Towels or aprons, for instance, which Paul had handled used to be carried to the sick, and they recovered from their ailments, or the evil spirits left them.
13 But there were also some wandering Jewish exorcists who undertook to invoke the name of Jesus over those who had the evil spirits, saying, "I command you by that Jesus whom Paul preaches."
14 There were seven sons of one Sceva, a Jew of high-priestly family, who were doing this.
15 "Jesus I know," the evil spirit answered, "and Paul I have heard of, but who are you?"
16 And the man in whom the evil spirit was sprang on two of them, over-mastered them both, and treated them with such violence, that they fled from the house stripped of their clothes and wounded.
