If man sends a get to his wife and then catches up with the messenger, or sends a messenger after the original messenger, and says to him, “The get which I gave you is annulled”, then it is annulled. If the husband arrives at his wife before [the messenger] or sends a messenger to her and says, “The get which I sent to you is annulled”, then it is annulled. Once the get has reached her hand, he cannot annul it.

Originally, a husband would bring together a court wherever he was and annul the get. Rabban Gamaliel the Elder established that this should not be done, because of tikkun olam. Originally the husband would change his name, or his wife’s name, or the name of his town or of his wife’s town. Rabban Gamaliel the Elder established that he should write, “The man so-and-so or any name that he has,”; “the woman so-and-so or any name that she has,” because of tikkun olam.

A widow is paid back [her kethubah] from the property of orphans only by taking an oath. [When the court] refrained from imposing an oath on her, Rabban Gamaliel the Elder established that she could take any vow which the orphans wanted and collect her kethubah. Witnesses sign their names on a get because of tikkun olam. Hillel instituted the prosbul because of tikkun olam.

A [non-Jewish] slave [of a Jew] was taken captive and then ransomed [by a third party]: If [he is ransomed] to be a slave he goes back to slavery. If [he is ransomed] as a free man he does not go back to slavery. Rabban Shimon ben Gamaliel says: in either case he goes back to slavery. If a man makes his slave a pledge [for a debt] to another man and then he emancipates him, according to the “letter of the law” the slave is not liable to do anything. But because of tikkun olam we force his [second] master to emancipate him and he [the slave] writes a document for his purchase price. Rabban Shimon ben Gamaliel says that the slave does not write the document but rather the one who emancipates him.

One who is half a slave and half free works for his master one day and for himself one day, the words of Beth Hillel. Beth Shammai said to them: you have set things right for the master but you have not set things right for the slave. He cannot marry a female slave because he is already half free, and he cannot marry a free woman because he is half a slave. Shall he then decease [from having children]? But wasn’t the world only made to be populated, as it says, “He did not create it as a waste, he formed it to be inhabited” (Isaiah 45:18)? Rather because of tikkun olam we compel his master to emancipate him and he writes a document for half his purchase price. Beth Hillel retracted [their opinion and] ruled like Beth Shammai.

If a man divorces his wife because of ill-repute, he cannot remarry her. If because of a vow, he cannot remarry her. Rabbi Judah says: [if he divorces her] for vows which she made in front of many people, he may not remarry her, but if for vows which she did not make in front of many people, he may remarry her. Rabbi Meir says: [if he divorces her] for a vow which requires the investigation of a sage, he may not remarry her, but if for one which does not require the investigation of a sage, he may remarry her. Rabbi Eliezer says: they only forbid that one because of that one. Rabbi Yose son of Rabbi Judah said: a case happened in Sidon of a man who said to his wife, “Konam, if I do not divorce you”, and he did divorce her, and the Sages permitted him to remarry her because of tikkun olam.

A man divorces his wife because she is an aylonit: Rabbi Judah says he may not remarry her, But the sages say that he may remarry her. She marries someone else and has children from him and then demands her ketubah settlement [from her first husband]: Rabbi Judah said, they say to her, “Your silence is better than your speaking.”

If a man sells himself and his children to a Gentile, he is not to be redeemed but his children are to be redeemed after the death of their father. If a man sells his field to a Gentile, and an Israelite bought it back, he has to bring, the purchaser must bring first fruits from it, because of tikkun olam.
