In the siddurim commonly in use today, on the Shabbat before Rosh Chodesh, we pray that we should be blessed to have "chaim she'ein bahem busha uchlima, a life that has no shame or disgrace". Being shamed is a most awful experience, and to embarrass someone in public is equated with murder (Bava Metzia 58b).
I had the privilege of learning in Rav Herschel Schachter’s shiur at Yeshiva University for four years, in the days before he was universally recognized as one of the outstanding Torah sages. His impact on my learning is immeasurable. One of the most striking things I learned in his shiur is how to say, “I don’t know”. We learned that there is no embarrassment in not knowing – even for great scholars. This humility is a most important, yet often lacking, trait in many a Torah (or any other) scholar.
A common feature of Talmudic editing is to group together a series of statements made by the same person.
