Human behavior often oscillates between silent malice and reckless outbursts, both of which carry deep social and personal consequences. The primary approach among commentators is that quiet physical gestures—like a subtle wink or a nod [מצודת ציון]—are the tools of someone who wishes to cause harm but fears acting openly [אבן עזרא, עמנואל הרומי]. These hidden signals take many forms. They might be used to incite another person toward wrongdoing [רש"י], to sabotage business dealings [רלב"ג, אמרי דעת], or to mock a righteous individual for observing commandments [אלשיך]. Sometimes, the person making these gestures believes no one notices or treats the act as a harmless joke. In reality, such behavior sows suspicion, anger, and trouble throughout society [ביאור שטיינזלץ]. In a more specific scenario, these secret signals might be directed inappropriately at a married woman, ultimately bringing grief to her family [עמנואל הרומי].
These deceitful actions inevitably result in sadness, though perspectives differ on who bears this pain. One view argues that the victim suffers the most. Because the malicious intent is never voiced aloud, the perpetrator's anger remains unresolved, leaving the victim in a state of continuous anxiety, never knowing when the hidden threat will materialize [מצודת דוד]. Conversely, the grief may fall upon the perpetrator himself, either as a direct punishment for his actions [אבן עזרא] or as the future sorrow he will experience when witnessing the eventual success of the righteous people he once mocked [אלשיך]. Taking a different psychological approach, the cause and effect can be reversed: an internal sadness is what corrupts a person's nature, damaging their physical well-being and ruining their ability to clearly observe and understand reality [אמרי דעת].
A completely different and positive perspective views the concept of these physical gestures through the idea of cutting or breaking. In this light, it represents an individual fiercely battling their own negative inclinations and breaking their unhealthy desires. While this intense internal struggle causes temporary suffering and sadness, it ultimately yields immense spiritual benefit [אמרי דעת].
In sharp contrast to the secretive plotter stands the fool, who lacks all verbal restraint and openly declares his wicked intentions or mockery [רלב"ג, אלשיך]. Because his reckless words are public, they inevitably lead to his downfall. He traps himself in his own hasty plans and faces punishment [ביאור שטיינזלץ, עמנואל הרומי]. Yet, there is a certain advantage to this lack of a filter. By venting all of his anger through loud boasting, the fool exhausts himself. His rage quickly subsides, making him far less dangerous in the end than the silent, cunning schemer [מצודת דוד].
