True wisdom is not merely an accumulation of intellectual knowledge or a basic understanding of reality; it is a profound force capable of transforming a person's character and outward disposition. The primary approach among commentators is that no one in the world is as important, joyful, and worthy as one who has attained such wisdom [רש"י, מצודת דוד, צאינה וראינה]. A truly wise individual possesses the rare ability to penetrate the absolute depths of any matter [מצודת דוד, שטיינזלץ]. Rather than engaging in endless, futile calculations, they seek the true meaning of existence and accurately interpret the Torah [אבן עזרא, תורה תמימה].
This profound understanding also manifests as the practical ability to compromise and bridge opposing forces [תעלומות חכמה]. Throughout history, this mastery has been embodied by extraordinary figures: Adam identifying the essence of animals, Daniel unraveling hidden mysteries and dreams, Moses ascending to the heavens, the Israelites receiving the Torah, and even God Himself [רש"י, תורה תמימה, צאינה וראינה]. Moses demonstrated this mediating wisdom when he stepped between God and the Israelites during the crisis of the Golden Calf [רש"י, תורה תמימה, צאינה וראינה]. Similarly, God applied this diplomatic grace to reconcile righteous leaders, such as King Hezekiah and the prophet Isaiah, ensuring the dignity of both was preserved [תורה תמימה, נחל אשכול].
The internal acquisition of wisdom does not remain hidden; its effects are immediately visible on the outside. Wisdom actively clears anger from the heart, replacing it with a radiant joy that softens the face and makes a person's words naturally beloved and accepted by others [מצודת דוד, אבן עזרא]. Sometimes, this illumination is quite literal. It recalls the divine radiance that shone from Moses so intensely that people were struck with awe, or the crowns of light bestowed upon the Israelites at Mount Sinai [רש"י, תורה תמימה, צאינה וראינה]. Even in everyday study, a scholar's face visibly brightens when they successfully resolve a complex question [תורה תמימה].
As wisdom brings light, it also fundamentally alters a person's natural harshness or arrogance. The primary approach among commentators is that this transformation is deeply positive. Wisdom cultivates humility, gradually shifting innate stubbornness, pride, and anger into gentle moderation [מצודת דוד, אבן עזרא, שטיינזלץ]. This internal shift is evident when the powerful human intellect willingly bows in submission to God's commands, even when those directives contradict natural logic [תעלומות חכמה]. It is also reflected in social hierarchies, such as when an imposing king softens his stern demeanor out of pure respect for a scholar standing before him in a court of law [נחל אשכול].
Conversely, a sudden change in demeanor can also reflect a state of loss or embarrassment. A scholar's face falls when confronted with a question they cannot answer, much like Moses' expression shifted when God did not immediately resolve a dilemma regarding purity. In a similar vein, both Adam and the Israelites suffered a tragic alteration in their appearance, losing their divine radiance as a direct consequence of their sins [תורה תמימה]. A uniquely different perspective suggests that unchecked arrogance and harshness do not change for the better, but rather provoke natural opposition. Because a rigid, prideful disposition repels those around it, it is considered a moral imperative to actively despise such arrogance [תורה תמימה, מנחת שי].
