Acts 16:23-28

23And when they had laid many stripes on them, they threw them into prison, commanding the jailer to keep them securely.

24Having received such a charge, he put them into the inner prison and fastened their feet in the stocks.

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

26Suddenly there was a great earthquake, so that the foundations of the prison were shaken; and immediately all the doors were opened and everyone’s chains were loosed.

27And the keeper of the prison, awaking from sleep and seeing the prison doors open, supposing the prisoners had fled, drew his sword and was about to kill himself.

28But Paul called with a loud voice, saying, “Do yourself no harm, for we are all here.”
