And when they had laid many stripes upon them, they cast them into prison, charging the jailor to keep them safely:
Who, having received such a charge, thrust them into the inner prison, and made their feet fast in the stocks.
And at midnight Paul and Silas prayed, and sang praises unto God: and the prisoners heard 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 every one's bands were loosed.
And the keeper of the prison awaking out of his sleep, and seeing the prison doors open, he drew out his sword, and would have killed himself, supposing that the prisoners had been fled.
But Paul cried with a loud voice, saying, Do thyself no harm: for we are all here.
Then he called for a light, and sprang in, and came trembling, and fell down before Paul and Silas,
And brought them out, and said, Sirs, what must I do to be saved?
And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house. Acts 16:23-31
