Nedarim9: 9
פּוֹתְחִין לָאָדָם בִּכְבוֹד עַצְמוֹ וּבִכְבוֹד בָּנָיו. אוֹמְרִים לוֹ: ,,אִלּוּ הָיִיתָ יוֹדֵעַ שֶׁלְּמָחָר אוֹמְרִין עָלֶיךָ: 'כָּךְ הִיא וֶסְתּוֹ שֶׁל פְּלוֹנִי, מְגָרֵשׁ אֶת נָשָׁיו', וְעַל בְּנוֹתֶיךָ יִהְיוּ אוֹמְרִין: 'בְּנוֹת גְּרוּשׁוֹת הֵן; מָה רָאֲתָה אִמָּן שֶׁל אֵלּוּ לְהִתְגָּרֵשׁ?' ”. וְאָמַר: אִלּוּ הָיִיתִי יוֹדֵעַ שֶׁכֵּן — לֹא הָיִיתִי נוֹדֵר!” — הֲרֵי זֶה מֻתָּר.
They can find grounds to annul a person's neder by [reason of] his own honor or the honor of his children. They say to him: “If you would have known that tomorrow they would say about you: `Such is the habit of So-and-so —- he divorces his wives,' and about your daughters they will say: `They are daughters of a divorced woman; what did their mother see to bring about her divorce?' [would you have vowed?].” If he said: “Had I known that this would be so, I would not have vowed!” —- it is permitted.
