This week's learning is sponsored by Michael and Ariella Radwin in honor of Danny Sadinoff and Rebecca Perlin on the 30th anniversary of the invention of Hebcal. "Danny and Rebecca, your commitment to Torah learning and Israel continue to be an inspiration to the Radwin family." Rav Gidal said in the name of Rav three more things (in addition to one in Nedarim 7b). 1. One can swear to fulfill a mitzva even though theoretically we are already “sworn in” from Matan Torah and a swear cannot be valid if one has already sworn to do something. If so, how does this work? 2. One can say they will get up early to learn something specific and it will be a valid vow. How can this be understood in light of the issue raised above? 3. One who says to one’s friend: "I will get up early and learn this chapter" should show up before the friend. One who saw in a dream that they were ex-communicated need ten learned people to dissolve the ex-communication. What are they to do if they can't find ten people who are learned? If one saw in the dream the person who ex-communicated them, can they find this person and not need to find ten learned people to dissolve it? If in the dream the ex-communication was dissolved, one still has to go through the process to dissolve it. Why?  Ravina's wife took a vow and he asked Rav Ashi if he could be a messenger to explain her reasons for regret to get the vow annulled. Rabbi Ashi said that he could but only if he went to a court already in existence. The Gemara learns three laws from this story. Regarding permitting ex-communication, the law is less strict. Why? They cite a drasha in the name of Rabbi Yehuda bar Ilai in which he extrapolates a verse in Malachi 3:20 that the sun will come and heal those who do not use God’s name in vain. Reish Lakish interprets the verse in a different way - it is referring to the righteous and the wicked in the world to come - there is no place called hell, but the righteous and the wicked will be in the same place and God will take out the sun and it will heal the righteous and burn the wicked.
