Study Guide Nedarim 14 Today's daf is sponsored by Art Gould for the refuah shleima of his wife, Carol Robinson, Karina Gola bat Huddah. "This is dedicated to the healing of my beloved wife and in gratitude to our Hadran family for all the notes and messages of support and in general just holding us in their hearts as we go through this difficult period." The Gemara gives two explanations as to how the Mishna can be explained according to Rabbi Yehuda's opinion, but the second explanation is rejected. What is the source of the halacha that one can take a vow by attaching it to another vowed item, but not a forbidden item? Why is it not possible to learn from the same verse to also include a forbidden item? The Mishna stated that the one who vows that he will not benefit from his wife with the words "She is forbidden to be like my mother" should be strict and undo the vow. But this is contradicted by an express braita. Abaye and Raba each resolve this in a different manner. Raba distinguished between a Torah scholar and an am haaeretz. Proof that the law sometimes distinguishes between these groups and requires annulling a vow only for an am haaretz can be learned from a braita about one who takes a vow on a Torah. The Gemara brings the braita in its entirety and discusses a difficulty with one of the lines of the braita and brings three resolutions. The Mishna says that one who says a vow not to sleep or not to talk or not to walk, must keep the vow. This Mishna will be further explained in Nedarim 15. The Gemara brings a dispute between Rav Yehuda in the name of Rav and Rav Nachman regarding one who said "I vow (konam) my eyes not to sleep today if I sleep tomorrow." Are they allowed to sleep today, and we will assume they will be careful tomorrow not to sleep so as not the break his vow, or do we tell them they cannot sleep today so that if they sleep tomorrow, the vow will not be broken? In the event that the declaration was said in the opposite direction  "My eyes will be konam to sleep tomorrow if I sleep today" both agree that one need not be careful not to sleep today as the fulfillment of the vow is tomorrow and that we can assume people will be careful about. Whereas in the previous case, it was only fulfillment of the condition that was tomorrow and that, perhaps, people are less careful about.
