Acts 16:25-26

Amplified Bible, Classic Edition

²⁵ But about midnight, as Paul and Silas were praying and singing hymns of praise to God, and the [other] prisoners were listening to them,

²⁶ Suddenly there was a great earthquake, so that the very foundations of the prison were shaken; and at once all the doors were opened and everyone’s shackles were unfastened.
