Acts 16:16-17

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. She followed after Paul and us and kept screaming and shouting, “These men are servants of the Most High God! They are proclaiming to you the way of salvation!”
