Megillah Shiur#53 YCQ - May 13, 2025 - What is the difference between a neder and a nedava? What is the difference betwen a neder and a shavua? Is there a kiyum aseh when one fulfils any and every neder? When does one violate bal t'acher when not bringing a karban? Who are the four people lacking kapara? Is there a problem in observing a zecher to Hakhel? How does a mikveh differ from a ma'ayan? Who is metamei b'mishkav and moshav? Why does the level of tumah not go down one level in mishkav? Why did the Russians close down Volozhin? A kohen has to avoid which tumas? Can a woman be tamai nidah yet muteres to her husband? For how long is a man tamei after being with a zava gedolah?
