Now there was a man named Simon, who previously practiced magic in the city and amazed the people of Samaria, claiming to be someone great.

It happened that as we were on our way to the place of prayer, we were met by a slave-girl who had a spirit of divination [that is, a demonic spirit claiming to foretell the future and discover hidden knowledge], and she brought her owners a good profit by fortune-telling.
