17 She started following Paul around, calling everyone's attention to us by yelling out, "These men are working for the Most High God. They're laying out the road of salvation for you!" 18 She did this for a number of days until Paul, finally fed up with her, turned and commanded the spirit that possessed her, "Out! In the name of Jesus Christ, get out of her!" And it was gone, just like that.
Matthew Henry's Commentary on Acts 16:17-18
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.
