כִּֽי־יִקַּ֥ח אִ֛ישׁ אִשָּׁ֖ה וּבְעָלָ֑הּ וְהָיָ֞ה אִם־לֹ֧א תִמְצָא־חֵ֣ן בְּעֵינָ֗יו כִּי־מָ֤צָא בָהּ֙ עֶרְוַ֣ת דָּבָ֔ר וְכָ֨תַב לָ֜הּ סֵ֤פֶר כְּרִיתֻת֙ וְנָתַ֣ן בְּיָדָ֔הּ וְשִׁלְּחָ֖הּ מִבֵּיתֽוֹ׃
Gdy pojmie kto żonę, a stanie się jej małżonkiem, i zdarzy się, że nie znajdzie upodobania w oczach jego, ponieważ znalazł w niej co sprosnego, niech napisze jej list rozwodny, i da w rękę jej, a puści ją z domu swego;
Mishnah Kiddushin
A woman is acquired in three ways and acquires herself in two: She is acquired by money, by document, or by intercourse. “By money”: Bet Shammai says: a denar or the equivalent of a denar; Bet Hillel says: a perutah or the equivalent of a perutah. And how much is a perutah? An eighth of an Italian issar. And she acquires herself by divorce or by her husband's death. A yevamah is acquired by intercourse. And she acquires herself by halitzah or by the yavam’s death.
Mishnah Eruvin
One may make the side-posts out of anything, even something that is alive. But Rabbi Yose prohibits this. It also causes defilement as the covering of a tomb, But Rabbi Meir makes pure. One may write on them gittin, But Rabbi Yose the Galilean declares it unfit.
Mishnah Gittin
They write [a get] with any material, with ink, with arsenic, with red chalk, with gum or with sulfate of copper or with anything which is lasting. It may not be written with liquids or with fruit juice or with anything that is not lasting. They write [a get] on anything: on an olive leaf, on the horn of an ox and he must give her the ox, or on the hand of a slave--and he must give her the slave. Rabbi Yose the Galilean says: they do not write [a get] on anything living or on food.
