Acts 19:1-20 New King James Version (NKJV)
19 And it happened, while Apollos was at Corinth, that Paul, having passed through the upper regions, came to Ephesus. And finding some disciples 2 he said to them, “Did you receive the Holy Spirit when you believed?”
So they said to him, “We have not so much as heard whether there is a Holy Spirit.”
3 And he said to them, “Into what then were you baptized?”
So they said, “Into John’s baptism.”
4 Then Paul said, “John indeed baptized with a baptism of repentance, saying to the people that they should believe on Him who would come after him, that is, on Christ Jesus.”
5 When they heard this, they were baptized in the name of the Lord Jesus. 6 And when Paul had laid hands on them, the Holy Spirit came upon them, and they spoke with tongues and prophesied. 7 Now the men were about twelve in all.
8 And he went into the synagogue and spoke boldly for three months, reasoning and persuading concerning the things of the kingdom of God. 9 But when some were hardened and did not believe, but spoke evil of the Way before the multitude, he departed from them and withdrew the disciples, reasoning daily in the school of Tyrannus. 10 And this continued for two years, so that all who dwelt in Asia heard the word of the Lord Jesus, both Jews and Greeks.
11 Now God worked unusual miracles by the hands of Paul, 12 so that even handkerchiefs or aprons were brought from his body to the sick, and the diseases left them and the evil spirits went out of them. 13 Then some of the itinerant Jewish exorcists took it upon themselves to call the name of the Lord Jesus over those who had evil spirits, saying, “We exorcise you by the Jesus whom Paul preaches.” 14 Also there were seven sons of Sceva, a Jewish chief priest, who did so.
15 And the evil spirit answered and said, “Jesus I know, and Paul I know; but who are you?”
16 Then the man in whom the evil spirit was leaped on them, overpowered them, and prevailed against them, so that they fled out of that house naked and wounded. 17 This became known both to all Jews and Greeks dwelling in Ephesus; and fear fell on them all, and the name of the Lord Jesus was magnified. 18 And many who had believed came confessing and telling their deeds. 19 Also, many of those who had practiced magic brought their books together and burned them in the sight of all. And they counted up the value of them, and it totaled fifty thousand pieces of silver. 20 So the word of the Lord grew mightily and prevailed.
