[י' ניסן, ה'תשל"ג]
שלום וברכה!
העיקר
, ת"ח על ההערה
לרש"י
נדה מה: ד"ה וזאת. ולכאורה צ"ע שלא צירף רש"י ב' הפי' יחד ויהי' סימן שלם (ע"ד פי'
הב"ח
). ואין הזמ"ג לחפש בס'.
10 Nissan, 5733.
Shalom u'Vrachah!
The main point: thank you for your comment regarding Rashi on Niddah 45b and this matter. Seemingly, the question is why Rashi did not combine both explanations into one complete sign (until the explanation of the Bach). At present, there is no time to search in the sources.
Summary
The Rebbe acknowledges a scholarly question about Rashi's commentary and notes that further research will be needed when time allows.
