Acts 16:25-32 ESV
About midnight Paul and Silas were praying and singing hymns to God, and the prisoners were listening to 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 everyone’s bonds were unfastened. When the jailer woke and saw that the prison doors were open, he drew his sword and was about to kill himself, supposing that the prisoners had escaped. But Paul cried with a loud voice, “Do not harm yourself, for we are all here.” And the jailer called for lights and rushed in, and trembling with fear he fell down before Paul and Silas. Then he brought them out and said, “Sirs, what must I do to be saved?” And they said, “Believe in the Lord Jesus, and you will be saved, you and your household.” And they spoke the word of the Lord to him and to all who were in his house.
