32 Ketubot 13/9-11

(9) [With regard to] two [men], who each produced promissory notes on the other one, Admon says, "[The holder of the last dated note can say,] 'If I owed you, how could you borrow from me?'"And the Sages say, "This one collects [on] his promissory note, and this one collects on his promissory note."

(10) There are three lands [within the Land of Israel] with regard to marriages: Judea, across the Jordan [River], and the Galilee. One may not [forcibly] remove [his wife from one land to another even to move] from a town to a town, or from a city to a city; but within the same land one may remove her from a town to a town, or from a city to a city, but not from a town to a city, nor from a city to a town. One may remove her from an inferior dwelling to a superior dwelling, but not from a superior dwelling to an inferior dwelling. Rabbi Shimon ben Gamliel says, "Not even from an inferior dwelling to a superior dwelling, because [even] a superior dwelling may occasion [sickness]."

(11) One may [forcibly] bring anyone to the Land of Israel, but one may not remove anyone. One may [forcibly] bring anyone to Jerusalem, but one may not remove anyone. [This law applies] both to men and to women. If a man married a woman in the Land of Israel, and divorced her in the land of Israel, he pays her [the amount of her ketubah] with the money of the Land of Israel. If he married a woman in the Land of Israel, and divorced her in Cappadocia, he pays her with the money of the Land of Israel. If he married a woman in Cappadocia, and divorced her in the Land of Israel, he pays her with the money of the Land of Israel. R. Shimon says, "He pays her with the money of Cappadocia." If he married a woman in Cappadocia, and divorced her in Cappadocia, he pays her with the money of Cappadocia.
