Today's daf is sponsored by Sylvia Klein in loving memory of her mother, Lila Klein, Leah bat Yosef v'Pasha, who passed away on Hoshana Raba in 2017. "A lifelong learner herself, she loved sharing the joys of Judaism with her preschoolers. And her wisdom and humor with us, her children." Today's daf is sponsored by Blima Storchein Slotzki in loving memory of Rivka bat Tina and Yitzhak Tzvi. There are two different interpretations of Rabbi Meir's opinion about a sale/betrothal performed with money unwittingly - is it considered meila or not and if so, is betrothal to a woman effective or not?  Theiropinions are analyzed and questions are raised against them. The Gemara then determines the halakha for betrothal performed using maaser sheni and hekdesh - the former like Rabbi Meir and the latter like Rabbi Yehuda. Questions are raised against the ruling like Rabbi Yehuda in maaser, based on tannaitic sources that seem to indicate otherwise. The difficulties are resolved.
