In Martina Cole's book "Revenge," the quote "He who brings trouble to his family will inherit only wind, and the fool will be servant to the wise" from Proverbs 11:29 conveys a powerful message about the consequences of one's actions. It suggests that individuals who cause strife and discord within their families or relationships will ultimately receive nothing of value in return. This highlights the importance of harmony and the detrimental impact of negative behavior on familial connections.

The second part of the quote illustrates the dynamics of wisdom and foolishness, suggesting that those who act foolishly will find themselves subservient to those who possess wisdom. In the context of the story, this underlines the idea that thoughtful, wise characters are ultimately more successful and respected, while foolish actions lead to downfall and servitude. Cole's narrative likely weaves these themes throughout the characters' journeys, emphasizing the moral lessons inherent in the consequences of their choices.
