משלי, פרק כ״ו, פסוק ז׳

The power of a proverb or a piece of wisdom depends entirely on the person speaking it. In the wrong hands, profound insight loses its value and can even become twisted. A natural parallel exists between a physical disability and mental incompetence, illustrating how a tool of wisdom becomes meaningless when wielded by a fool. The imagery centers on the legs of a lame person [מצודת ציון].

The primary approach among commentators focuses on the idea of uneven height. Just as a lame person might have bent legs where one is higher than the other, preventing a straight and steady walk, a proverb spoken by a fool is inherently misaligned. A foolish person cannot properly match a parable to its intended lesson. They tend to add or remove details until the true meaning is distorted and the original message is completely lost [רלב״ג, מצודת דוד, ביאור שטיינזלץ].

Taking a different view, other commentators understand the physical imagery to represent frailness or dryness. In this sense, the lame person's legs are withered and entirely useless for walking. In the exact same way, a parable told by a fool lacks intelligence and serves no practical purpose, much like a body without functioning legs [אבן עזרא, מלבי״ם]. This fundamental uselessness also highlights the danger of relying on a fool to deliver a message. A foolish person lacks orderly and correct speech, just as crippled legs are unfit for walking [עמנואל הרומי].

Another perspective views the concept of height as a symbol of distance and an unbridgeable gap. To a lame person, the healthy legs of an ordinary person appear high up and completely unreachable. Similarly, deep wisdom and Torah study seem distant and unattainable to a fool. The fool uses this perceived distance as a convenient excuse, arguing that wisdom is simply too mysterious, strict, and demanding, leading him to avoid learning altogether [רש״י, חומת אנך, עמנואל הרומי].

Finally, this sense of elevation can be seen as a reflection of the fool's own arrogance. Even though he is intellectually crippled, with no real mental foundation to support him, he falsely raises himself up. He uses parables and expressions of wisdom to demand respect from others and to justify his own misguided path in life [אלשיך].
