Acts 19:6-16

6 And when Paul had laid his hands upon them, the Holy Spirit came on them; and they spake with tongues, and prophesied.
7 And they were in all about twelve men.
8 And he entered into the synagogue, and spake boldly for the space of three months, reasoning and persuading [as to] the things concerning the kingdom of God.
9 But when some were hardened and disobedient, speaking evil of the Way before the multitude, he departed from them, and separated the disciples, reasoning daily in the school of Tyrannus.
10 And this continued for the space of two years; so that all they that dwelt in Asia heard the word of the Lord, both Jews and Greeks.
11 And God wrought special miracles by the hands of Paul:
12 insomuch that unto the sick were carried away from his body handkerchiefs or aprons, and the evil spirits went out.
13 But certain also of the strolling Jews, exorcists, took upon them to name over them that had the evil spirits the name of the Lord Jesus, saying, I adjure you by Jesus whom Paul preacheth.
14 And there were seven sons of one Sceva, a Jew, a chief priest, who did this.
15 And the evil spirit answered and said unto them, Jesus I know, and Paul I know, but who are ye?
16 And the man in whom the evil spirit was leaped on them, and mastered both of them, and prevailed against them, so that they fled out of that house naked and wounded.
