Acts 19:9

19:9 But when some were stubborn and refused to believe, reviling the Way before the congregation, he left them and took the disciples with him, addressing them every day in the lecture hall of Tyrannus.

Acts 19:13-16

19:13 But some itinerant Jewish exorcists tried to invoke the name of the Lord Jesus over those who were possessed by evil spirits, saying, “I sternly warn you by Jesus whom Paul preaches.” 19:14 (Now seven sons of a man named Sceva, a Jewish high priest, were doing this.) 19:15 But the evil spirit replied to them, “I know about Jesus and I am acquainted with Paul, but who are you?” 19:16 Then the man who was possessed by the evil spirit jumped on them and beat them all into submission. He prevailed against them so that they fled from that house naked and wounded.
