Acts 16:28

‘But Paul cried with a loud voice, saying, “Do yourself no harm, for we are all here.” '

Paul, seeing him in the light of his glowing lamp, recognised his intention and yelled to him not to harm himself as all the prisoners were still safe. Those that were there were possibly traumatised and sheltering from falling masonry, and, hindered by their manacles, unable to find a way to climb out of the dungeon, or even afraid to do so, and they may only have been but few.

The jailer would undoubtedly be astonished that this man sought to save his life. He had known such care and concern from comrades-in-arms but never from a prisoner whom he had treated so brutally. Here were these men who had caused these strange occurrences and instead of cursing him and bringing down maledictions on him they were concerned to save his life. It was all very strange. Indeed it was uncanny.
