אלשיך — ובא אשר לו הבית והגיד לכהן לאמר כנגע נראה לי בבית

Q — Why does the homeowner's required declaration use the curious phrase 'כנגע נראה *לי* בבית' rather than the simpler 'כנגע ראיתי בבית'?

A — The wording is itself a vidui. 'לי' here functions in the sense of *for me / on my account* (like 'ועשה לי מטעמים,' 'וצודה לי'). The homeowner is being instructed to say not 'I saw a plague-like spot' (a neutral observation) but 'a plague-like spot appeared *because of me* in my house' — admitting that the affliction is no accident, that 'אין דבר משולל השגחתו יתברך,' and recognizing the chesed Hashem is doing by starting from the house rather than the body. The Rambam's gradient is well-known — house, then garments, then skin — and this verse is calibrated to be said at the very first step, when teshuvah is still cheap and the lesson is still easy to absorb. A person who can sincerely say 'נראה לי' is already on the path to 'חזר בו - יטהר הבית.'
