Nedarim 18 - Shabbat November 12, 18 Cheshvan

Today's daf is sponsored by Beth Kissileff Perlman in honor of the lives and in memory of the deaths of the 11 kedoshim killed at Tree of Life, New Light and Dor Hadash synagogues in Pittsburgh on October 27, 2018. Joyce Fienberg, Richard Gottfried, Rose Mallinger, Jerry Rabinowitz, Cecil Rosenthal, David Rosenthal, Bernice Simon, Sylvan Simon, Dan Stein, Mel Wax and Irving Younger. The third question against Rav Huna is answered and a fourth question is raised and answered. When the Mishna stated that one is not liable for an oath on an oath, Rava infers that one is not liable but the oath exists, meaning that if the first oath is undone, the second will move into its place. If the language of a vow is unclear, one rules stringently. But if the language was ambiguous and the one who vowed explained the meaning of their words to be referring to a language that would not be a valid vow, then we can rule leniently and it is not considered a vow. The Mishna brings different examples of cases where one would rule leniently or stringently. This Mishna contradicts an explicit Mishna that one rules leniently in cases of nazir, which is a type of vow.
