Reference for Nedarim 135:4

אי אמרי' מיגז גייז לקייא אי אמרינן מקליש קליש איסורא בעלמא הוא מאי

The scholars propounded: Does the husband cut [the vow] or weaken [it]?<span class="x" onmousemove="('comment',' Does he completely nullify half the vow, leaving the other half for the father, or does he weaken the whole vow, whilst actually nullifying nothing of it? [The same question applies equally to the father (Ran).] ');">⁷</span> How does this problem arise? E.g., If she [the betrothed maiden] vowed not to eat the size of two olives [of anything],<span class="x" onmousemove="('comment',' Nothing whatsoever may be eaten of that which is forbidden, but the size of an olive is the smallest quantity for which punishment is imposed. ');">⁸</span>
