Acts 16:25-31

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

26 Suddenly there was a violent earthquake, which shook the prison to its foundations. At once all the doors opened, and the chains fell off all the prisoners.

27 The jailer woke up, and when he saw the prison doors open, he thought that the prisoners had escaped; so he pulled out his sword and was about to kill himself.

28 But Paul shouted at the top of his voice, "Don't harm yourself! We are all here!"

29 The jailer called for a light, rushed in, and fell trembling at the feet of Paul and Silas.

30 Then he led them out and asked, "Sirs, what must I do to be saved?"

31 They answered, "Believe in the Lord Jesus, and you will be saved - you and your family."
