Romans 1:25

” It happened that as we were going to the place of prayer, a slave-girl having a spirit of divination met us, who was bringing her masters much profit by fortune-telling. This girl followed Paul and the rest of us, shouting, “These men are servants of the Most High God, who are telling you the way to be saved.” She kept this up for many days. Finally Paul became so troubled that he turned around and said to the spirit, “In the name of Jesus Christ I command you to come out of her!” At that moment the spirit left her. When the owners of the slave girl realized that their hope of making money was gone, they seized Paul and Silas and dragged them into the marketplace to face the authorities.”
