Paul comes to Ephesus and finds about twelve disciples who know only John's baptism and have not even heard that there is a Holy Spirit. Paul explains that John told people to believe in the one who was coming after him, Jesus. They are baptized in the name of the Lord Jesus, Paul lays his hands on them, and the Holy Spirit comes on them and they speak in tongues and prophesy.
For three months Paul reasons in the synagogue about the kingdom of God. When some become hardened, he teaches daily in the hall of Tyrannus for two years, so that all who live in Asia hear the word of the Lord. God does extraordinary miracles by Paul's hands: handkerchiefs and aprons that had touched his body are carried to the sick, and diseases and evil spirits leave them.
Seven sons of Sceva, Jewish exorcists, try to invoke the name of the Jesus whom Paul preaches. The evil spirit answers that it knows Jesus and Paul, but not them; the man overpowers them and they flee naked and wounded. Fear falls on all, and the name of the Lord Jesus is extolled. Many confess their practices, and those who had practiced magic burn their books in the sight of all, worth fifty thousand pieces of silver. So the word of the Lord grows and prevails.
Paul resolves to go to Jerusalem and then to Rome. Then the silversmith Demetrius, who makes silver shrines of Artemis, gathers the craftsmen and says that Paul is turning away many people and that the worship of the great goddess is in danger. The city fills with confusion and rushes to the theater, and for two hours they cry out: Great is Artemis of the Ephesians! The town clerk quiets the crowd, says there are courts for complaints and that they risk being charged with rioting, and dismisses the assembly.
