Acts 8:5-8

5Philip [the evangelist] went down to the city of Samaria and began proclaiming Christ (the Messiah, the Anointed) to them.

6The crowds gathered and were paying close attention to everything Philip said, as they heard [the message] and saw the [miraculous] signs which he was doing [validating his message].

7For unclean spirits (demons), shouting loudly, were coming out of many who were possessed; and many who had been paralyzed and lame were healed.

8So there was great rejoicing in that city.
