Acts 16:16-19, 23, 25-26, 29-31

And it came to pass, as we were going to the place of prayer, that a certain maid having a spirit of divination met us, who brought her masters much gain by soothsaying. The same following after Paul and us cried out, saying, These men are servants of the Most High God, who proclaim unto you the way of salvation. 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. But when her masters saw that the hope of their gain was gone, they laid hold on Paul and Silas, and dragged them into the marketplace before the rulers

And when they had laid many stripes upon them, they cast them into prison, charging the jailor to keep them safely

But about midnight Paul and Silas were praying and singing hymns unto God, and the prisoners were listening to them; and suddenly there was a great earthquake, so that the foundations of the prison-house were shaken: and immediately all the doors were opened; and every one’s bands were loosed.

And he called for lights and sprang in, and, trembling for fear, fell down before Paul and Silas, and brought them out and said, Sirs, what must I do to be saved? And they said, Believe on the Lord Jesus, and thou shalt be saved, thou and thy house.
