Words are more than a simple tool for sharing thoughts; they carry a destructive power that can easily become a trap for the speaker. For a foolish person, every attempt at communication inevitably spirals into conflict and personal damage. The primary approach among commentators is that a fool simply lacks the ability to speak calmly or peacefully. Instead, his speech is constantly marked by provocation, a raised voice, and teasing [רש"י, רלב"ג, מצודת דוד]. This constant friction is not always born out of malicious intent; often, it is merely the result of his own ignorance and a deeply flawed way of expressing himself [ביאור שטיינזלץ]. Another perspective suggests that this dynamic plays out through a tendency to intrude, as the fool constantly inserts himself into the arguments of other people [עמנואל הרומי].
On a deeper, spiritual level, this behavior reflects a direct rebellion against God. Unlike a simpleton who might only harbor doubts and hesitate, the fool intentionally uses his speech to argue against divine providence [מלבי"ם].
The inevitable result of this combative behavior is severe harm. By constantly provoking others, the fool literally invites strong, shattering, and wounding blows upon himself [רלב"ג, מצודת ציון, עמנואל הרומי]. The primary approach among commentators is that his aggravating words directly cause people to rise up and strike him physically.
This self-inflicted damage also extends into the legal realm. When standing before a court, the fool's own argumentative words serve as witnesses that incriminate him. Once the judges rightfully rule against him, he loudly complains to the public, claiming he has been struck down and treated unjustly [אלשיך].
The progression of this downfall can be understood through the difference between superficial and deep speech. Outward, shallow expressions are what initially spark the fight. However, as the fool speaks more deeply to defend his arguments against the laws of wisdom, the conflict escalates from a mere argument into actual, physical violence [מלבי"ם].
