Acts 16:16-19

16 It happened, as we were going to prayer, that a certain girl having a spirit of divination met us, who brought her masters much gain by fortune telling.  17 Following Paul and us, she cried out, "These men are servants of the Most High God, who proclaim to us the way of salvation!"  18 She was doing this for many days.  But Paul, becoming greatly annoyed, turned and said to the spirit, "I charge you in the name of Jesus Christ to come out of her!" It came out that very hour.  19 But when her masters saw that the hope of their gain was gone, they seized Paul and Silas, and dragged them into the marketplace before the rulers.
