Acts 19:9-15

⁹But when divers were hardened, and believed not, but spake evil of that way before the multitude, he departed from them, and separated the disciples, disputing daily in the school of one Tyrannus.

¹⁰And this continued by the space of two years; so that all they which dwelt in Asia heard the word of the Lord Jesus, both Jews and Greeks.

¹¹And God wrought special miracles by the hands of Paul:

¹²So that from his body were brought unto the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them.

¹³Then certain of the vagabond Jews, exorcists, took upon them to call over them which had evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth.

¹⁴And there were seven sons of one Sceva, a Jew, and chief of the priests, which did so.

¹⁵And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye?
