Talmud for Ketubot 7:4
הַמַּדִּיר אֶת אִשְׁתּוֹ שֶׁלֹּא תֵלֵךְ לְבֵית אָבִיהָ, בִּזְמַן שֶׁהוּא עִמָּהּ בָּעִיר, חֹדֶשׁ אֶחָד יְקַיֵּם. שְׁנַיִם, יוֹצִיא וְיִתֵּן כְּתֻבָּה. וּבִזְמַן שֶׁהוּא בְעִיר אַחֶרֶת, רֶגֶל אֶחָד יְקַיֵּם. שְׁלֹשָׁה, יוֹצִיא וְיִתֵּן כְּתֻבָּה:
If one accepted his wife's vow not to go to her father's house — When he (her father) is with her in the same city, he keeps her one month and on the second he sends her out and gives her her kethubah. And when he is in a different city, he keeps her for one festival, and on the third he send her out and gives her her kethubah. [The gemara explains this Mishnah as follows: "He keeps her for one festival": When is this so, with the wife of an Israelite; but with the wife of a Cohein, he keeps her for two festivals and on the third he sends her out. Our Mishnah is in accordance with R. Yehudah, who distinguishes between the wife of an Israelite and the wife of a Cohein. The halachah is not in accordance with him.]
