קהלת, פרק י׳, פסוק ח׳

Human actions, particularly those driven by malice or carelessness, have a profound tendency to rebound upon the person who initiated them. Often, people find themselves trapped and harmed by the very schemes they designed to catch others. A person who digs a pit with the intention of trapping a friend will ultimately fall into that very same hole. Similarly, someone who breaks down a stone fence exposes themselves to hidden dangers. Snakes naturally seek shelter in the dark crevices between stones, and dismantling such a wall invites a sudden bite [רש״י, מצודת דוד, ביאור שטיינזלץ]. These parallel scenarios illustrate a fundamental truth about cause and effect [מצודת דוד]. A wise individual anticipates the consequences of their actions and carefully avoids these self-destructive paths, whereas a fool or a corrupt leader blindly walks into their own traps [אבן עזרא].

Throughout history, this principle of measure-for-measure justice has played out vividly. The concept of falling into one's own trap is reflected in the downfall of prominent oppressors. Pharaoh, who ruthlessly decreed that Israelite boys be thrown into the river, ultimately met his end drowning in the sea with his army [תורה תמימה, תעלומות חכמה]. Haman, who meticulously plotted to annihilate the Jewish people, saw his wicked plans collapse back onto his own head [תורה תמימה]. Additionally, this fate befell Nebuchadnezzar, whose royal lineage was cut short as a direct consequence of his arrogance in looting and misusing the sacred vessels of the Temple [רש״י, צאינה וראינה].

The imagery of breaking a wall and suffering a snake bite carries equally deep spiritual and historical significance. The primary approach among commentators views the wall as a symbol for the protective boundaries and regulations established by the Sages to safeguard the Torah. Someone who brazenly violates these spiritual boundaries exposes themselves to severe danger, symbolized by a snake bite, which represents a heavenly punishment [רש״י, תורה תמימה, צאינה וראינה]. Alternatively, the breached wall represents the physical walls of Jerusalem and the Temple, which were destroyed by Nebuchadnezzar, an act of destruction for which he was later severely punished [תעלומות חכמה]. Finally, the imagery is applied to the story of Dinah, the daughter of Jacob. Her decision to go out and observe the local women is seen as a breach in the protective wall of modesty. By breaking this boundary, she was harmed by Shechem the Hivite, whose very tribal name is linguistically connected to an ancient word for a snake [תורה תמימה].
