Study Guide Shabbat 6 Today's shiur is sponsored by Meryl and Harold Sasnowitz in memory of Malka bat Chaya Ettel and Mordechai and Toba Raizel bat Rochel and Zvi. Refuah Sheleima to Zvi ben Freida.   If one removes an item from the public domain to the private domain (or the reverse) through a collonade (status of karmelit), is one obligated or not? Debate between Ben Azai and the rabbis. The gemara questions the rabbis opinion who obligates - where do we have a precedent for obligated in a case like this? The gemara brings three answers - the first two are rejected as they are not similar enough. Rabbi Yochanan narrows Ben Azai's opinion and said he agrees with the rabbis that one would be obligated if one threw it and it only passed through the airspace of the collonade. The gemara quotes the Tosefta which defines each of the four domains and what is allowed or not by Torah and rabbinic law. The gemara then analyzes the wording - questions and then provides answers.
