Acts 19:8-20

8And 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. 9But 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 one Tyrannus. 10And this continued for the space of two years; so that all they that dwelt in Asia heard the word of the Lord Jesus, both Jews and Greeks. 11And God wrought special miracles by the hands of Paul: 12insomuch that unto the sick were brought handkerchiefs or aprons from his body, and the diseases departed from them, and the evil spirits went out from them. 13But certain of the strolling Jews, exorcists, took upon them to name over them that had the evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth. 14And there were certain men, seven sons of Sceva, a Jew, a chief priest, who did this. 15And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye? 16And the man in whom was the evil spirit, leaping upon them and mastering them, prevailed against them, so that they fled out of that house naked and wounded. 17And this became known to all, both Jews and Greeks, that dwelt at Ephesus; and fear fell upon them all, and the name of the Lord Jesus was magnified. 18Many also of them that had believed came, confessing, and declaring their deeds. 19And not a few of them that practiced magical arts brought their books together and burned them in the sight of all; and they counted the price of them, and found it fifty thousand pieces of silver. 20So mightily grew the word of the Lord and prevailed.
