Acts 16:22-27

22The crowd joined in the attack against Paul and Silas, and the magistrates ordered that they be stripped and beaten with rods. 23And after striking them with many blows, they threw them into prison and ordered the jailer to guard them securely. 24On receiving this order, he placed 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 other prisoners were listening to them. 26Suddenly a strong earthquake shook the foundations of the prison. At once all the doors flew open and everyone’s chains came loose.

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