Charles Ellicott Commentary Acts 16:18

"And this she did for many days. But Paul, being sore troubled, turned and said to the spirit, I charge thee in the name of Jesus Christ to come out of her. And it came out that very hour." — Acts 16:18 (ASV)

But Paul, being grieved...—It is obvious that the constant repetition of these clamorous cries must have been a hindrance to the Apostle’s work, disturbing him as he talked to the other women at the proseucha. Was it not right for him to do as his Master had done with the demoniacs of Gadara (see Notes on Matthew 8:28-34), and to restore the woman to her true self, by teaching her to distinguish between her longing for deliverance and the wild passions that hindered her from attaining it? And so he spoke, and the evil spirit came out the same hour. Here the history ends, as far as the young woman was concerned; but we can hardly think that she was left to drift back into ignorance and unbelief.

Would not such a one find shelter and comfort at the hands of the women who laboured with the Apostle (Philippians 4:2)? May we not think of her gratitude as showing itself in the gifts that were sent to the Apostle, upon whom she had unwillingly brought so much suffering (Philippians 4:15)?
