106 Gittin 4/7-9

(ז) הַמּוֹצִיא אֶת אִשְׁתּוֹ מִשּׁוּם שֵׁם רָע, לֹא יַחֲזִיר. מִשּׁוּם נֶדֶר, לֹא יַחֲזִיר. רַבִּי יְהוּדָה אוֹמֵר, כָּל נֶדֶר שֶׁיָּדְעוּ בוֹ רַבִּים, לֹא יַחֲזִיר. וְשֶׁלֹּא יָדְעוּ בוֹ רַבִּים, יַחֲזִיר. רַבִּי מֵאִיר אוֹמֵר, כָּל נֶדֶר שֶׁצָּרִיךְ חֲקִירַת חָכָם, לֹא יַחֲזִיר. וְשֶׁאֵינוֹ צָרִיךְ חֲקִירַת חָכָם, יַחֲזִיר. אָמַר רַבִּי אֱלִיעֶזֶר, לֹא אָסְרוּ זֶה אֶלָּא מִפְּנֵי זֶה. אָמַר רַבִּי יוֹסֵי בְּרַבִּי יְהוּדָה, מַעֲשֶׂה בְצַיְדָּן בְּאֶחָד שֶׁאָמַר לְאִשְׁתּוֹ, קוֹנָם אִם אֵינִי מְגָרְשֵׁךְ, וְגֵרְשָׁהּ. וְהִתִּירוּ לוֹ חֲכָמִים שֶׁיַּחֲזִירֶנָּה, מִפְּנֵי תִקּוּן הָעוֹלָם:

(ח) הַמּוֹצִיא אֶת אִשְׁתּוֹ מִשּׁוּם אַיְלוֹנִית, רַבִּי יְהוּדָה אוֹמֵר, לֹא יַחֲזִיר. וַחֲכָמִים אוֹמְרִים, יַחֲזִיר. נִשֵּׂאת לְאַחֵר וְהָיוּ לָהּ בָּנִים הֵימֶנּוּ, וְהִיא תוֹבַעַת כְּתֻבָּתָהּ, אָמַר רַבִּי יְהוּדָה, אוֹמְרִים לָהּ, שְׁתִיקוּתִיךְ יָפָה לִיךְ מִדִּבּוּרִיךְ:

(ט) הַמּוֹכֵר אֶת עַצְמוֹ וְאֶת בָּנָיו לְגוֹי, אֵין פּוֹדִין אוֹתוֹ, אֲבָל פּוֹדִין אֶת הַבָּנִים לְאַחַר מִיתַת אֲבִיהֶן. הַמּוֹכֵר שָׂדֵהוּ לְגוֹי וְחָזַר וּלְקָחָהּ מִמֶּנּוּ יִשְׂרָאֵל, הַלּוֹקֵחַ מֵבִיא מִמֶּנּוּ בִכּוּרִים, מִפְּנֵי תִקּוּן הָעוֹלָם:

(7) [With regard to] one who divorced his wife due to her bad reputation, he may not remarry her. If it was because of a vow [that she made], he may not remarry her. Rabbi Yehudah says, "[In the case of] any vow that was known to the public, he may not remarry her. [But for one] that was not known to the public, he may remarry her." Rabbi Meir says, "[In the case of] any vow that required the inspection of a Sage[to determine if it can be annulled], he may not remarry her. If it does not require inspection of a Sage, he may remarry her." Rabbi Eliezer said, "This one was only prohibited due to that one. Rabbi Yossi, son of Rabbi Yehudah, said, "There was an occurrence in Sidon with one man who said to his wife, "I take a vow if I do not divorce you, and he divorced her. The rabbis allowed them to remarry, due to Tikkun HaOlam.

(8) [With regard to] one who divorces his wife because she is an aiylonit [[a woman with arrested sexual development who cannot bear children], Rabbi Yehudah says, "He may not remarry her." The Sages say, "He may remarry her." If she married someone else, and she had children with him, and she demands her ketubah [from the first husband], Rabbi Yehudah says, "We say to her, 'Your silence is better than your speaking.'"

(9) [With regard to] one who sells himself and his children to a non-Jew, we do not redeem him. But we redeem the children after the death of their father. [With regard to] one who sells his field to a non-Jew, and a Jew buys it back from him, the buyer brings the first fruits from it, due to Tikkun HaOlam.
