משנה: אָמַר רִבִּי אֱלִיעֶזֶר. מָה אִם אִשָּׁה שֶׁקָּנָה הוּא לְעַצְמוֹ הֲרֵי הוּא מֵיפֵר נְדָרֶיהָ אִשָּׁה שֶׁקָּנוּ לוֹ מִן שָׁמַיִם אֵינוֹ דִין שֶׁיָּפֵר נְדָרֵיהָ. אָמַר לוֹ רִבִּי עֲקִיבָה לֹא. אִם אָמְרָת בְּאִשָּׂה שֶׁקָּנָה הוּא לְעַצְמוֹ שֶׁאֵין לָאֲחֵרִים רְשׁוּת בָּהּ תֹּאמַר בְּאִשָּׁה שֶׁקָּנוּ לוֹ מִן שָׁמַיִם שֶׁיֵּשׁ לָאֲחֵרִים רְשׁוּת בָּהּ. אָמַר לוֹ רִבִּי יְהוֹשֻׁעַ. עֲקִיבָה דְּבָרֶיךָ בִשְׁנֵי יְבָמִין מָה אַתָּה מֵשִׁיב עַל יָבָם אֶחָד. אָמַר לוֹ אֵין הַיְּבָמָה גְמוּרָה לְאִישָׁהּ כְּשֵׁם שֶׁהָאֲרוּסָה גְּמוּרָה לְבַעֲלָהּ.
MISHNAH: Rebbi Eliezer said, if he can dissolve vows for a wife which he himself acquired, so much more that he should be able to dissolve for a wife which Heaven acquired for him. Rebbi Aqiba answered him: No. What you say is about a wife which he himself acquired, where nobody else has any authority over her; what can you say about the wife which Heaven acquired for him, where others have authority over her? Rebbi Joshua said to him, Aqiba, your words apply to two levirs. What can you reply about one levir? He said to him, the sister-in-law does not belong completely to her man as the wife belongs completely to her husband.
