Sotah 29 - April 27 - 6 Iyar

Study Guide Sotah 29 The Gemara continues and explains the dispute between Rabbi Yishmael and Rabbi Akiva in the drasha on the verses about  with whom can she not have relations and what else is the sotah prohibited to do? There is another source for the rule that a  doubt regarding impurity is treated strictly only if there is a person involved who theoretically could have known if it was impure.  Why do we need two sources for this? Where did Rabban Yochanan ben Zakkai learn that a second vessel defiles a third if not from the verse of Rabbi Akiva? He learned it from a kal vachomer from a tvul yom. If so, why did he fear that others would reject this? On what basis would they reject it? From where do we derive that there is a fourth degree of impurity in sacrificial items? Rabbi Yosi learns it from a kal vachomer from a mechusar kipurim. Rabbi Yochanan raises a difficulty with the kal vachomer.
