About this episode
Study Guide Shabbat 18 Today's shiur is dedicated by Leah Brick in memory of her father-in-law, Murray Brick, Mordechai ben Chaim Yosef Gershon z"l and by Jonathan, Kenny and Danny Sadinoff in memory of their father, Frank Sadinoff, Efraim Mordechai ben Menachem Mendel z"l and for a refuah sheleima to Pesach Yehoshua ben Tova Chaya. The gemara asks according to which approach regarding kneading does the mishna hold - by which one can be obligated for kneading by putting something in water that will thicken without actually kneading with one's hands or a utensil? The gemara bring various braitot with cases similar to our mishna - where an act is done before Shabbat that will continue through Shabbat - and tries to figure out if the source is authored by Beit Shamai or Beit Hillel. It is complicated as there seem to be many exceptions to the rule. Once the gemara explains the reasons for the exceptions, they bring relevant halachot that can be derived from the reasons given for the exceptions.
