16 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 fortune-telling. 17 She followed Paul and us, crying out, "These men are servants[1] of the Most High God, who proclaim to you the way of salvation." 18 And this she kept doing for many days. Paul, having become greatly annoyed, turned and said to the spirit, "I command you in the name of Jesus Christ to come out of her." And it 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.
