(ב) בָּרִאשׁוֹנָה הָיָה עוֹשֶׂה בֵית דִּין בְּמָקוֹם אַחֵר וּמְבַטְּלוֹ. הִתְקִין רַבָּן גַּמְלִיאֵל הַזָּקֵן שֶׁלֹּא יְהוּ עוֹשִׂין כֵּן, מִפְּנֵי תִקּוּן הָעוֹלָם. בָּרִאשׁוֹנָה הָיָה מְשַׁנֶּה שְׁמוֹ וּשְׁמָהּ, שֵׁם עִירוֹ וְשֵׁם עִירָהּ. וְהִתְקִין רַבָּן גַּמְלִיאֵל הַזָּקֵן שֶׁיְּהֵא כוֹתֵב, אִישׁ פְּלוֹנִי וְכָל שֵׁם שֶׁיֵּשׁ לוֹ, אִשָּׁה פְלוֹנִית וְכָל שׁוּם שֶׁיֵּשׁ לָהּ, מִפְּנֵי תִקּוּן הָעוֹלָם:
(2) The mishna relates that initially, a husband who wished to render the bill of divorce void would convene a court elsewhere and render the bill of divorce void in the presence of the court before it reached his wife. Rabban Gamliel the Elder instituted an ordinance that one should not do this, for the betterment of the world. ...Rabban Gamliel the Elder instituted that the scribe should write in the bill of divorce: The man so-and-so, and any other name that he has, and: The woman so-and-so, and any other name that she has. The reason for this ordinance was for the betterment of the world, as perhaps the people of a different city would not recognize the name written in the bill of divorce, and would claim that this bill of divorce does not belong to her.
And Rabbi Yitzḥak said: A person’s sentence is torn up on account of four types of actions. These are: Giving charity, crying out in prayer, a change of one’s name, and a change of one’s deeds for the better. An allusion may be found in Scripture for all of them: Giving charity, as it is written: “And charity delivers from death” (Proverbs 10:2); crying out in prayer, as it is written: “Then they cry to the Lord in their trouble, and He brings them out of their distresses” (Psalms 107:28); a change of one’s name, as it is written: “As for Sarai your wife, you shall not call her name Sarai, but Sarah shall her name be” (Genesis 17:15), and it is written there: “And I will bless her, and I will also give you a son from her” (Genesis 17:16); a change of one’s deeds for the better, as it is written: “And God saw their deeds” (Jonah 3:10), and it is written there: “And God repented of the evil, which He had said He would do to them, and He did not do it” (Jonah 3:10).
