16 Now it happened, as we went to prayer, that a certain slave girl possessed with a spirit of divination met us, who brought her masters much profit by fortune-telling. 17 This girl followed Paul and us, and cried out, saying, "These men are the servants of the Most High God, who proclaim to us the way of salvation." 18 And this she did for many days. But Paul, greatly annoyed, turned and said to the spirit, "I command you in the name of Jesus Christ to come out of her." And he came out that very hour.

Commentary on Acts 16:16-24
(Read Acts 16:16-24)
Satan, though the father of lies, will declare the most important truths, when he can thereby serve his purposes. But much mischief is done to the real servants of Christ, by unholy and false preachers of the gospel, who are confounded with them by careless observers. Those who do good by drawing men from sin, may expect to be reviled as troublers of the city. While they teach men to fear God, to believe in Christ, to forsake sin, and to live godly lives, they will be accused of teaching bad customs.
