How can there be a mitzvah to rebuke even one hundred times if there is also a mitzvah not to say something that will not be heard?

This source-based Torah study examines the question: How can there be a mitzvah to rebuke even one hundred times if there is also a mitzvah not to say something that will not be heard? The canonical Hebrew discussion develops the issue through the weekly Torah portion and the classical sources cited there, preserving the distinctions and tensions of the original unit. This localized layer is a discovery-oriented summary rather than a full translation of the article, and it does not add a new halakhic, medical, legal, historical, mystical or empirical ruling or claim beyond the canonical source. Any practical conclusion remains subject to the unit’s canonical review status.
