Acts 16:24-26 ESV
Having received this order, he put them into the inner prison and fastened their feet in the stocks. About midnight Paul and Silas were praying and singing hymns to God, and the prisoners were listening to them, and suddenly there was a great earthquake, so that the foundations of the prison were shaken. And immediately all the doors were opened, and everyone’s bonds were unfastened.
