קהלת, פרק ז׳, פסוק כ׳

Human existence is naturally filled with flaws, making the pursuit of absolute perfection an impossible goal. Even the greatest people make mistakes, a reality that highlights the constant need for self-examination and repentance. The primary approach among commentators is that this reality explains an earlier warning in the book of Ecclesiastes against trying to be overly righteous. In a flawed world, perfectly righteous people simply do not exist. No matter how much effort a person makes, it is impossible to completely avoid doing wrong in action, speech, or thought [אבן עזרא, ביאור שטיינזלץ, תעלומות חכמה]. Since consistently doing good without ever failing is an unattainable state, even the most completely righteous individuals require atonement [אבן עזרא, תורה תמימה]. Knowing this fundamental truth about human nature leads to a practical conclusion: true wisdom lies in using this awareness to regularly examine one's own actions and to quickly repent whenever mistakes occur [רש״י, מצודת דוד, צאינה וראינה].

While the standard understanding views these failures as regular sins, another perspective defines the concept of sin in this context as missing the mark, much like a stone slinger missing a target. This view focuses specifically on public officials, such as those who collect and distribute charity. These individuals strive to do good but inevitably make errors, as they cannot know hidden truths or decide with absolute certainty who truly deserves financial support and who does not [תורה תמימה].

An additional layer of interpretation connects the failure directly to the good deed itself. Sometimes, a person tries to do a good deed but, due to a lack of knowledge and understanding, actually fails while trying to perform a Commandment. This does not stem from bad intentions, but rather from a lack of Torah wisdom. The human body is compared to a small city controlled by ten main organs—the eyes, ears, hands, feet, mouth, and heart—which naturally tend to follow physical desires. The only way to overcome their control and perform good deeds properly, without stumbling, is by acquiring the wisdom of the Torah, which guides a person's actions along the correct path [אלשיך, צאינה וראינה].
