Charles Ellicott Commentary Acts 16:28

"But Paul cried with a loud voice, saying, Do thyself no harm: for we are all here." — Acts 16:28 (ASV)

Do thyself no harm.—Few and simple as the words are, they are eminently characteristic of the love and sympathy which burned in St. Paul’s heart. For him, the suicide which others would have admired, or, at least, would have thought of without horror, would have been the most terrible of all forms of death. He could not bear the thought that even the jailer who had thrust him into the dungeon, should so perish in his despair.
