Acts 16:26-30
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?
