Acts 16:26-29
16:26 Suddenly a great earthquake occurred, so that the foundations of the prison were shaken. Immediately all the doors flew open, and the bonds of all the prisoners came loose.
16:27 When the jailer woke up and saw the doors of the prison standing open, he drew his sword and was about to kill himself, because he assumed the prisoners had escaped.
16:28 But Paul called out loudly, “Do not harm yourself, for we are all here!”
16:29 Calling for lights, the jailer rushed in and fell down trembling at the feet of Paul and Silas.
