Speech holds the profound power to act as a deadly weapon or a vital tool for rescue, and the choice rests entirely in human hands. Calculated speech requires time and planning [מלבי״ם]. Wicked individuals use this premeditation to orchestrate harm against others. This damage can take the form of direct violence, such as murder and theft, or it can be executed indirectly through gossip, slander, and false testimony [רש״י, מלבי״ם, מצודת דוד, עמנואל הרומי]. Often, the driving forces behind these actions are hatred and a desire for revenge. However, some possess a cruelty so deep that they inflict pain without any personal benefit, acting much like a snake that bites out of pure, instinctual malice [עמנואל הרומי]. The threat they pose is especially severe because they frequently disguise their malicious plans with smooth, pleasant words that appear harmless on the surface [אלשיך, ביאור שטיינזלץ].
In stark contrast, upright individuals, who have values of justice and honesty deeply rooted in their nature, use the power of speech to dismantle these evil schemes. The primary approach among commentators is that their words serve to rescue innocent victims. When honest people uncover a malicious plot, they quickly warn the targets and expose the danger [רש״י, עמנואל הרומי]. If the threat involves false testimony, upright individuals acting in a court of law will thoroughly cross-examine the witnesses. They continue questioning until contradictions are revealed, thereby dismantling the lies and saving the accused from unjust punishment [רש״י, מצודת דוד].
Beyond rescuing innocent victims, there are different perspectives on who exactly benefits from this honest speech. Some explain that the wise and upright words of the righteous protect the righteous themselves, preventing them from falling into the traps set by the wicked [ביאור שטיינזלץ, מלבי״ם]. On the other hand, a completely different view suggests a vulnerability: upright people naturally look for the good in others and judge them favorably. Because of this, they might be deceived by the smooth talking of the wicked. In such a scenario, honest individuals might unknowingly use their voices to defend and save the wrongdoers, much like Isaac was misled by the words of Esau [אלשיך].
