Suddenly there was such a violent earthquake that the foundations of the prison were shaken. At once all the prison doors flew open, and everyone’s chains came loose.
The jailer woke up, and when he saw the prison doors open, he drew his sword and was about to kill himself because he thought the prisoners had escaped.
But Paul shouted, “Don’t harm yourself! We are all here!”
The jailer called for lights, rushed in and fell trembling before Paul and Silas.
