Final answer:
The excerpts provided do not directly answer the question about what Antonio's brothers tell him before they leave for war, and the specific book is not identified. Further context is needed to provide an accurate response.
Step-by-step explanation:
The student's question appears to relate to a book's storyline, notably a moment where a character's brothers impart some final words before leaving for war. The provided excerpts, however, do not contain specific dialogue from Antonio's brothers and thus do not directly answer the student's question. Without additional context or identifying the book in question, providing an accurate response is challenging. Therefore, as a tutor, the professional guidance is to advise the student to refer back to the specific text or provide additional details for proper assistance.
