משלי, פרק ל׳, פסוק ל״ג

The physical act of applying pressure yields entirely different results depending on the material being squeezed. This natural law serves as a profound metaphor for human behavior and character. The primary approach among commentators is to view this dynamic as a progression of cause and effect. When a person churns and presses milk, the result is good, sweet, and useful butter. However, violently squeezing a nose produces blood, causing pain and damage. In the exact same way, stirring up and squeezing out anger produces nothing but conflict and strife [רלב"ג, ביאור שטיינזלץ]. The moral lesson drawn from this progression is the immense value of silence. A person should avoid awakening their anger, as it inevitably leads to arguments and shameful words that ultimately disgrace them [אבן עזרא, מצודת דוד].

On a deeper psychological level, this dynamic serves as a warning against the common misconception that venting anger and negative thoughts cleanses and calms the soul. While blowing one's nose to remove waste leaves the body clean, expressing raw anger is compared to violently squeezing the flesh of the nose itself until it bleeds. This destructive action drains a person's vitality, defiles their speech, and causes self-inflicted harm. Instead of venting, the proper approach is to process and purify negative thoughts internally within the heart, much like churning butter requires striking the milk repeatedly inside a tightly closed and sealed vessel [אלשיך].

In the spiritual and intellectual realm, commentators apply this metaphor to the pursuit of wisdom and the study of God's laws. One perspective focuses on the deep humility required for learning. A student who is willing to humble themselves, ask questions even at the risk of looking foolish, and absorb a teacher's frustration for not understanding immediately, will eventually produce excellent and refined legal rulings, much like rich butter. Conversely, a student who keeps their mouth shut out of pride will be left speechless when asked to provide guidance [רש"י]. Another approach contrasts true wisdom with false ideas. Delving deeply into divine wisdom produces pure and clear understanding. On the other hand, investigating flawed and false philosophies generates corrupt conclusions, similar to drawing blood. Finally, harboring anger toward God's management of the world, such as questioning why the wicked prosper while the righteous suffer, will inevitably lead to rebellion and direct conflict with heaven [מלבי"ם].
