A long daf with much to discuss. When Erev Pesach falls out on Shabbat - do you get rid of chametz before Shabbat or on Shabbat? It may depend if your chametz is terumah or not. [Who's Who: R. Tzadok] Also: Nullifying chametz in your heart (mind), by saying out loud that you negate its existence - various cases when involvement in mitzvot or trouble necessitates this approach. What about consecrated food items (that aren't supposed to leave Jerusalem)? What amount of this kind of food (chametz or hekdesh) would be a violation? Also: Talmidei chachamim should not participate in feasts that are not mitzvah celebrations. Including a side point about a marital pairing that should not happen, and what happens if it would happen (and when it did happen). Also: The havoc wrought by talmidei chachamim attending non-mitzvah feast, or one who eats too much, or focuses too much on the food. Plus: How far one should go to marry the daughter of a talmid chacham. Or to marry one's daughter to a talmid chacham. And if that population is not available to you, the Gemara lists a hierarchy of preference of what kind of profession to go for - as long as you avoid the "amei ha-aretz"/ ignoramuses, with very colorful language describing how bad that would be. Plus the parable of grapes on the vine, when like marries like. The language is so harsh... It makes R. Akiva's presentation of the harsh language all the more valuable.
