In literary terms, what does the phrase "know them by their fruits" imply?

The phrase "know them by their fruits" implies evaluating someone's character by their actions. This expression originates from the biblical context, where it suggests that the true nature of a person can be discerned through the results of their actions or behavior, much like how a tree can be judged by the quality of its fruit. This idea emphasizes that outward appearances can be misleading, and it is ultimately a person's deeds and their impact on the world that reveal their true character. Evaluating someone's actions offers a more genuine insight into who they are as individuals, rather than relying on superficial assessments or material indicators.
