דברים, פרק י״ג, פסוק ט״ו

When a grave rumor surfaces that an entire city has been led astray into idolatry, the judicial system must initiate a rigorous, meticulous legal process before passing judgment. Acting on behalf of the entire nation, the high court cannot rely on hearsay [אם למקרא]. This demand for a comprehensive investigation stems from the unique nature of the crime. Unlike a false prophet who publicly displays signs, or an individual inciter who operates directly with another person, the subversion of an entire city reaches the court only as a distant rumor. Furthermore, the reality of an entire city unanimously agreeing to commit such a severe offense is exceedingly rare, compelling the judges to exercise extreme caution [רמב״ן, טור הארוך, ביאור יש״ר, קיצור בעל הטורים].

The mandate to thoroughly inquire, investigate, and ask establishes the foundation for cross-examining witnesses in all capital cases. The primary approach among commentators divides this interrogation into two main categories: primary investigations and secondary examinations. The primary investigations consist of seven mandatory questions focusing on the precise time and place of the event—pinpointing the Sabbatical cycle, year, month, day, hour, and exact location [רש״י, מזרחי, תורה תמימה, מלבי״ם]. The purpose of this precision is to create an opportunity to refute the witnesses should they be testifying falsely. If a witness is unable to answer even one of these core questions, the entire testimony is immediately invalidated [רבנו בחיי, ברטנורא, רש״ר הירש, משכיל לדוד].

In contrast, the secondary examinations involve minor details surrounding the event, such as the color of the perpetrator's clothing or the specific type of weapon used [ברכת אשר, בכור שור, צאינה וראינה]. During this phase, if witnesses simply cannot remember a detail, their testimony remains valid as long as there are no direct contradictions between their accounts [ברטנורא]. Some commentators structure this investigative process sequentially: first, establishing the core facts of the event and whether a proper warning was given; second, administering the seven mandatory questions of time and place; and finally, asking numerous secondary questions to fully uncover the truth. The demand to conduct this process thoroughly emphasizes that a judge must not only be a scholar of Torah law but also possess practical worldly wisdom, ensuring he is not easily deceived into issuing a false ruling [אדרת אליהו].

Once all stages of the investigation are complete, if the testimonies align perfectly without contradiction, the initial rumor is established as a clear, objective, and stable reality [רלב״ג, ביאור יש״ר, שטיינזלץ, רש״ר הירש]. It is then confirmed that the inhabitants were indeed led astray to worship idols [העמק דבר, שטיינזלץ]. The emphasis that this abomination occurred internally, right in the midst of the nation, carries both legal and moral weight. Legally, this specific phrasing includes converts and freed slaves residing in the city, ensuring they are counted as part of the population when determining if the majority of the city has sinned [תורה תמימה, מלבי״ם, צפנת פענח]. Morally, the fact that such a massive betrayal could take root points to a profound societal failure. A tragedy of this magnitude can only develop when society turns a blind eye to minor infractions, allowing the neglect to swell until an entire city abandons God [חתם סופר].
