Ketubot 3 - Shabbat July 9. 10 Tamuz

Today's daf is sponsored by Emma Rinberg in loving memory of her father, Dr Eric Glick, Yitchak Nissan ben Yaacov. "He died on the 10th of Tammuz, 32 years ago, aged 62. With his warm smile, beautiful voice and healing hand I think of him daily and am comforted that he watches over us." For what reason did Rava claim that one cannot claim "oness" (it wasn't circumstances beyond my control) regarding a get? He claims it is on account of women who are overly humble or not at all. If the man really doesn't intend for the get to be valid and based on the rabbis, it is valid (as they decided not to accept a claim of oness), how can the rabbis uproot a Torah law? The answer is that they don't assume the get is valid - they uproot the kiddushin (annul the marriage). How do they have the power to do that? After answering this question, the Gemara brings a different version of Rava's statement claiming he said the opposite - one can claim ones in a case of get. All the sources they brought in Ketubot 2b to try to prove Rava's statement are now brought to question Rava's statement. All the explanations that were given to reject them as proven in Ketubot 2b are not used to respond to the difficulties. Since the takana of getting married on Wednesday is based on the court system instituted by Ezra of Mondays and Thursdays, it would not be relevant before that or in a time where courts meet any day. However, since there is the issue of having three days to prepare the meal, one can be flexible only if the meal is fully prepared. In order to properly explain the issue with preparing the meal, the Gemara brings a braita which explains it. The braita also describes an exception to the Wednesday rule. In a case of danger, one can get married on Tuesday and in a case of oness, one can even get married on Monday. What is meant by "danger" and "oness"?
