As we were going to the place of prayer, we were met by a slave girl who had a spirit of divination and brought her owners much gain by soothsaying. She followed Paul and us, crying, “These men are servants of the Most High God, who proclaim to you the way of salvation.” And this she did for many days. But Paul was annoyed, and turned and said to the spirit, “I charge you in the name of Jesus Christ to come out of her.” And it came out that very hour.
–Acts 16:16-18
