משלי, פרק ט״ז, פסוק כ״ז

A person who abandons all moral boundaries does not merely stumble into doing wrong. Instead, he dedicates active effort and deep thought to harming others, driven by pure malice rather than a desire for personal gain. This type of reckless individual has completely cast off the yoke of heaven [ביאור שטיינזלץ, מלבי״ם, אלשיך, אמרי דעת]. He acts like someone physically digging a pit to trap others [מצודת ציון]. The primary approach among commentators is that this serves as a metaphor for a person who plots evil in his heart. Rather than settling for the harm that easily crosses his path, he actively seeks out schemes, applying his intellect to invent new ways to cause damage [רלב״ג, מצודת דוד, עמנואל הרומי]. He carefully prepares traps to cause others to stumble through his actions or his words [ביאור שטיינזלץ]. Offering a unique perspective, another interpretation connects this deliberate plotting to the concept of preparing a feast, suggesting that committing evil is the actual food and life force that sustains such an immoral person [עמנואל הרומי].

The destruction this person causes is heavily tied to his speech, which acts as a scorching weapon [רש״י, מצודת ציון, עמנואל הרומי]. The primary approach among commentators is that malice burns inside him like a fire until he is forced to release it into the world. His words are sharp, painful, and corrupting, inflaming his listeners to the point that his mouth inflicts even more damage than his silent thoughts [רש״י, רלב״ג, ביאור שטיינזלץ, עמנואל הרומי, מצודת דוד]. Some add that this destructive fire rests on every part of his lips, a trait highly characteristic of an informer [אבן עזרא].

In contrast, other viewpoints suggest this fiery speech is not openly offensive, but rather deeply hypocritical. According to this approach, the person speaks with the passionate fire of fake love to disguise the ambush he has secretly laid for his companion [מלבי״ם]. Another perspective views the fire as a defensive reaction. Because the traps he sets are often discovered, when he is caught in his wrongdoing, he responds with heated anger and loud excuses, as if a fire is burning on his lips, all to mask his sheer audacity [אלשיך].
