The conflict between good and evil sometimes reaches an extreme breaking point. Wicked individuals do not simply succeed in their own lives; they actively and openly direct their hostility toward those who uphold law and morality. This harsh reality often raises difficult questions, especially when God appears to remain silent while good people suffer in the face of blatant wickedness [אלשיך].
The initial stage of this attack begins in secret. It involves deep planning and calculated thought directed entirely toward doing evil, with the specific goal of harming and destroying the righteous. This kind of scheming always represents a malicious intention meant to bring pain to another [מלבי״ם]. Yet, alongside this hidden plotting, there is a visible, physical reaction: the grinding and gnashing of teeth [רש״י, מצודת ציון].
The motives behind this physical display vary. The primary approach among commentators is that it expresses intense rage, giving the wicked a wild and frightening appearance [מצודת ציון, מצודת דוד, ביאור שטיינזלץ]. However, others identify deeper psychological drivers. It can represent a cruel anticipation and a premature sense of victory, where the wicked person spots an opportunity to strike and grinds his teeth as if to declare that his victim is finally caught [רד״ק]. Alternatively, this action is a calculated tactic used during a good person's moment of weakness or crisis, intended to instill fear and further break their spirit [אבן עזרא]. Taking a different perspective, the act may not be a physical threat at all, but rather a display of deep mockery and contempt. It reflects a desire to see the righteous suffer simply because of their moral and pious lifestyle [מאירי].
Confronted with such a menacing reality, a good person must respond on two distinct levels. On a practical level, this hostility serves as a warning to actively reject the wicked and avoid any association or company with them [אבן עזרא]. On the level of faith, there is absolutely no room for despair, even when evil people plot and threaten while God seems to do nothing but laugh at their efforts. This divine silence is merely a period of waiting for the day of judgment. God sees and knows everything, and the very plots and destructive tools the wicked prepare will ultimately become the cause of their own downfall [מלבי״ם].
