Acts 16:24

22The multitude rose up together against them and the magistrates tore their clothes from them, then commanded them to be beaten with rods.

23When they had laid many stripes on them, they threw them into prison, charging the jailer to keep them safely.

24Having received such a command, he threw them into the inner prison and secured their feet in the stocks.

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

26Suddenly 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 loosened.
