Acts 16:26-28

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 unfastened.

²⁷The jailer was awakened from sleep and saw the open prison doors; he drew his sword and was about to kill himself, because he thought that the prisoners had escaped.

²⁸But Paul shouted with a loud voice, saying, “Do not harm yourself, because we are all here.”
