Acts 16:25-34 - The Conversion Of The Philippian Jailer
25 At midnight, Paul and Silas prayed, and lauded God. And the prisoners heard them. 26 And suddenly, there was a great earthquake, so that the foundation of the prison was shaken, and by and by all the doors opened, and every man's bonds were loosed. 27 When the keeper of the prison waked out of his sleep, and saw the prison doors open, he drew out his sword and would have killed himself, supposing the prisoners had been fled.
28 But Paul cried with a loud voice saying, "Do thyself no harm, for we are all here."
29 Then he called for a light and sprang in, and came trembling, and fell down before Paul and Silas, 30 and brought them out and said, "Sirs, what must I do to be saved?"
31 And they said, "Believe on the Lord Jesus, and thou shalt be saved and thy household." 32 And they preached unto him the word of the Lord, and to all that were in his house. 33 And he took them the same hour of the night and washed their wounds, and was baptised, with all that belonged unto him, straightway. 34 When he had brought them into his house, he set meat before them, and joyed that he with all his household believed on God.
