Acts 19:8-20

8Paul entered the synagogue and spoke boldly there for three months, arguing persuasively about the kingdom of God. 9But some of them became obstinate; they refused to believe and publicly maligned the Way. So Paul left them. He took the disciples with him and had discussions daily in the lecture hall of Tyrannus.

10This went on for two years, so that all the Jews and Greeks who lived in the province of Asia heard the word of the Lord. 11God did extraordinary miracles through Paul,

12so that even handkerchiefs and aprons that had touched him were taken to the sick, and their illnesses were cured and the evil spirits left them. 13Some 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.” 14Seven sons of Sceva, a Jewish chief priest, were doing this. 15One day the evil spirit answered them, “Jesus I know, and Paul I know about, but who are you?”

16Then 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. 17When 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 honor. 18Many of those who believed now came and openly confessed what they had done. 19A number who had practiced sorcery brought their scrolls together and burned them publicly. When they calculated the value of the scrolls, the total came to fifty thousand drachmas. A drachma was a silver coin worth about a day’s wages.

20In this way the word of the Lord spread widely and grew in power.
