Acts 16:16-18

One day when we were going down to the place of prayer we met a slave girl possessed by an evil spirit. She earned her masters a great deal of money by fortune-telling. This girl followed Paul and the rest of us around, shouting, “These men are the servants of Almighty God. They are telling you how to be saved!” She went on doing this for several days. This bothered Paul so he turned around and told the spirit, “I command you in the name of Jesus Christ to leave her!” The spirit immediately left her.
