Final answer:
There is no mention of Paul trying to stop Mrs. Jewis in the provided text excerpts, which seem to be from different sources of literature and discuss topics unrelated to the query.
Step-by-step explanation:
The passage provided originates from a dramatic script and is a mix of direct speech and action which suggests that it's a part of a play or other similar form of literature, rather than a factual event. Hence, there is no account of someone named Paul trying to stop Mrs. Jewis from pouring brine on Leslie within the text snippets you have provided. Instead, the excerpts mention moments from different narratives, such as the dialogue between Mrs. Hale and Mrs. Peters from the play 'Trifles' by Susan Glaspell, a passage from early Christian hagiography discussing Thecla and Paul, and a snippet from 'Incidents in the Life of a Slave Girl' by Harriet Ann Jacobs. Each of these accounts contains discussions of various societal and moral issues but does not mention the specific event you are asking about concerning Paul and Mrs. Jewis.
