Megillah Shiur#54 YCQ - Jun 10, 2025 - What level of tumah is a ba'al keri? Who cannot enter walled cities? How many times does a tamei meis need to emerse in a mikveh to become tahor? Who needs to be tovel in a ma'ayan? When are toldos like avos? Why do we not say miksas hayom ke'kulo by Shabbos? Do we say kiksas hayom ke'kulo on the vev of day seven of shiva? What differences are there between a metzora musgar and muchlat?
