Acts 16:22-26

²²And the multitude rose up together against them: and the magistrates rent their garments off them, and commanded to beat them with rods.

²³And when they had laid many stripes upon them, they cast them into prison, charging the jailor to keep them safely:

²⁴who, having received such a charge, cast them into the inner prison, and made their feet fast in the stocks.

²⁵But about midnight Paul and Silas were praying and singing hymns unto God, and the prisoners were listening to them;

²⁶and 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.
