It's a wild story. Paul and Silas are beaten and thrown into jail, shackled and placed in solitary confinement. And how do they respond? By praying and singing a robust hymn to God, much to the surprise of the other inmates. 

Then, without warning, a huge earthquake! The jailhouse tottered, every door flew open, all the prisoners were loose. Startled from sleep, the jailer saw all the doors swinging loose on their hinges. Assuming that all the prisoners had escaped, he pulled out his sword and was about to do himself in, figuring he was as good as dead anyway, when Paul stopped him: “Don’t do that! We’re all still here! Nobody’s run away!” ("The Message" by Eugene Peterson)
