משלי, פרק י״ד, פסוק כ״ג

Human effort, whether physical or mental, naturally yields results, while empty chatter leads only to loss. The primary approach among commentators focuses on the practical value of hard work and manual labor. In any job or business where a person works hard to make a living, their effort brings tangible benefit and profit [מצודת ציון, ביאור שטיינזלץ, רש״י, אבן עזרא, עמנואל הרומי]. Naturally, the more a person works, the greater their return [רלב״ג]. In stark contrast, words spoken without accompanying action only create lack. While increasing effort brings an advantage, multiplying words provides no benefit and often leads to mistakes and loss [רלב״ג, מצודת דוד]. Engaging in unnecessary conversation is viewed as a fundamental flaw [עמנואל הרומי], unless the speech possesses deep inner value, such as the study of Torah [אלשיך]. On a physical level, this concept also applies to craftsmanship; anything a person actively shapes and creates with their hands holds inherent value, unlike empty speech which is entirely a waste [אלשיך].

Beyond physical labor, there is a profound emotional and spiritual dimension to this dynamic, focusing on the internal work of sadness and mourning. While popular belief often views sadness as purely harmful, commentators explain that there is a massive advantage when a person feels a heavy heart due to sincere repentance or a deep reflection on the fragility of life. This internal emotional effort humbles the person, subdues their negative desires, and prevents arrogance from taking root [אלשיך, אמרי דעת, ביאור שטיינזלץ]. In times of pain or suffering, quiet reflection and internalization allow a person to earn spiritual reward. However, if a person chooses instead to use their voice to complain and express anger toward God regarding their circumstances, they forfeit that reward. In this case, their spoken words directly cause their own spiritual loss [מלבי״ם].

Looking at the broader context of the surrounding teachings, the destructive nature of speech also takes on a social meaning. The empty talk refers specifically to the harmful advice of people who plot evil and teach others to follow their path. Ultimately, it is their own negative speech and malicious planning that backfire, leading them directly into poverty and ruin [עמנואל הרומי].
