Nedarim 66A

לומר שאין מקרעין שטר כתובה.

In fact, arrangements are made with creditors. Rather, R' Akiva is saying that they do not tear the document of the marriage contract. Even if in practice he is left with enough to survive on, the debt remains in force, so that when he will have more money, she will be paid in full.

מתני׳ פותחין בימים טובים ובשבתות. בראשונה היו אומרים: אותן הימים ⁠— מותרין, ושאר כל הימים אסורין. עד שבא רבי עקיבא ולימד שהנדר שהותר מכללו ⁠— הותר כולו.

Mishnah: If one vowed that certain food or drink or all food and drink be forbidden to him, the halakhic authorities may broach dissolution by raising the issue of Festivals and Shabbatot. They ask him whether he realized at the time he stated his vow that he would have to uphold it on these festive days as well. At first they said that on those days that he did not intend to include in his vow, that item is permitted, but on all the rest of the days, food and drink are still forbidden by his vow, until R' Akiva came and taught that a vow that is partially dissolved is dissolved entirely.

כיצד? אמר ״קונם שאיני נהנה לכולכם״, הותר אחד מהן ⁠— הותרו כולן.

How so? In the case of one who said to a group of people: I will not benefit from all of you as it is konam for me, if benefit from one of them was permitted for whatever reason, benefit from all of them is permitted.

״שאיני נהנה לזה ולזה״, הותר הראשון ⁠— הותרו כולן, הותר האחרון ⁠— האחרון מותר וכולן אסורין. הותר האמצעי, הימנו ולמטה ⁠— מותר, הימנו ולמעלה ⁠— אסור.

However, if one said: I will not benefit from this one and from that one as it is konam for me, then if benefit from the first one was permitted for whatever reason, benefit from all of them is permitted. But if benefit from the last one was permitted, benefit from the last one alone is permitted, but benefit from all the others is forbidden, as the benefit from each is considered to have been prohibited by a separate vow. If benefit from the middle one was permitted, then from him and below, i.e., all those enumerated after him, benefit is permitted; from him and above, i.e., those listed before him, benefit is forbidden.
