Acts 19:6-16

6 And when Paul had imposed his hands on them, the Holy Ghost came upon them: and they spoke with tongues and prophesied.
7 And all the men were about twelve.
8 And entering into the synagogue, he spoke boldly for the space of three months, disputing and exhorting concerning the kingdom of God.
9 But when some were hardened and believed not, speaking evil of the way of the Lord before the multitude, departing from them, he separated the disciples, disputing daily in the school of one Tyrannus.
10 And this continued for the space of two years, so that all who dwelt in Asia heard the word of the Lord, both Jews and Gentiles.
11 And God wrought by the hand of Paul more than common miracles.
12 So that even there were brought from his body to the sick, handkerchiefs and aprons: and the diseases departed from them: and the wicked spirits went out of them.
13 Now some also of the Jewish exorcists, who went about, attempted to invoke over them that had evil spirits the name of the Lord Jesus, saying: I conjure you by Jesus, whom Paul preacheth.
14 And there were certain men, seven sons of Sceva, a Jew, a chief priest, that did this.
15 But the wicked spirit, answering, said to them: Jesus I know: and Paul I know. But who are you?
16 And the man in whom the wicked spirit was, leaping upon them and mastering them both, prevailed against them, so that they fled out of that house naked and wounded.
