שופטים, פרק ט״ז, פסוק י״ז

Yielding to relentless pressure, a heavily guarded secret is finally brought into the light. Samson surrenders to Delilah's demands, laying bare the true source of his immense power and the exact method required to strip it away. By exposing his deepest hidden thoughts [מצודת דוד], he directly answers her two most pressing questions: what makes him so powerful, and how he can ultimately be bound and defeated [מלבי״ם]. He explains that a razor has never touched his head, as his hair has been left uncut since birth [מצודת ציון, ביאור שטיינזלץ]. Should his head be shaved, his extraordinary abilities would instantly vanish [מצודת דוד].

There is a subtle but profound difference between this honest confession and the false answers he gave her in the past. In his previous attempts to mislead her, he claimed that if his instructions were followed, he would become as weak as a single, particular man. This carefully chosen phrasing allowed him to avoid an outright lie, as the reference to a singular man implied an exceptional individual, meaning he would still retain his unique strength. Now, however, speaking the absolute truth, he admits that he will become like all other men, reduced to the ordinary weakness of anyone else [מלבי״ם].

Delilah immediately recognizes that he is no longer weaving tales. Several factors convince her of his honesty. First, he invokes the name of God, and she knows he would never use the Divine Name lightly. Second, his explanation of being dedicated to God from the womb perfectly matches his physical appearance, specifically his long, untamed hair. Furthermore, she may have already been aware of the story of an angel appearing to his mother before his birth, or he might have even sworn a formal oath to her. The convergence of all these details leaves no doubt in her mind that he has finally spoken the truth, prompting her to act swiftly and summon the Philistine leaders [אברבנאל].
