Acts 16:22-27

22The crowd joined the attack against them, and the magistrates tore the clothes off Paul and Silas and ordered them to be beaten with rods.

23After they had beaten them severely, they threw them into prison and commanded the jailer to guard them securely.

24Receiving such orders, he threw them in the inner cell and fastened their feet in the stocks.

25About midnight Paul and Silas were praying and singing hymns to God, and the rest of the prisoners were listening to them.

26Suddenly a great earthquake occurred, so that the foundations of the prison were shaken. Immediately all the doors flew open, and the bonds of all the prisoners came loose.

27When the jailer woke up and saw the doors of the prison standing open, he drew his sword and was about to kill himself, because he assumed the prisoners had escaped.
