Today's daf is sponsored by Rikki and Alan Zibitt in memory of Rikki's father, Mickey Carlin, Shevach ben Avraham v' Mita, whose 14th yahrzeit was on Thursday. "Daddy, we miss you every day." Rav Papa was marrying his son off to Abba Sura'ah's daughter when Yehuda bar Meriemar came to greet Rav Papa. Yehuda was hesitant to come in, as he was concerned Abba Sura'ah would raise the dowry on his account. After much insisting on the part of Rav Papa, Yehuda enters but remains silent. However, Abaa Sura'ah misunderstands the silence and in fact raises the dowry because of Yehuda's presence and gives all of his money to the dowry. When Yehuda finally speaks and explains himself, Abba Sura'ah wants to change his pledge, but Yehuda criticized him for turning back on his word. Rav Yeimar and Rava discuss the law in different cases where a woman sells her ketuba or rights to part of her ketuba to her husband. Would this mean that she forfeits the rights of her male children inheriting her ketuba in the event that she predeceases her husband? A woman who forgoes her rights to her ketuba to her husband, does she also lose her rights to receive continuous sustenance upon his death? If a woman is betrothed, is her fiance obligated to bury her (one of her rights of the ketuba)? Another right of the ketuba is that the estate of the husband will sustain the woman's daughters upon his death. Rav and Levi disagree about whether this ends at the time of their marriage or when they become a bogeret. Does the daughter give up her rights to sustenance at her betrothal or only at her marriage? Rav Yosef and Rav Chisda disagree and each prove their point with a logical argument. Two different versions are brought about who holds which position. A woman who "refuses" a marriage (mi'un), does she return to get sustained from the father's estate? Does the daughter of the yevama receive sustenance from the father's estate?
