Reference for Ketubot 3:5

כֵּיצַד שׁוֹתֶה בַעֲצִיצוֹ, אֲפִלּוּ הִיא חִגֶּרֶת, אֲפִלּוּ הִיא סוּמָא, וַאֲפִלּוּ הָיְתָה מֻכַּת שְׁחִין. נִמְצָא בָהּ דְּבַר עֶרְוָה, אוֹ שֶׁאֵינָהּ רְאוּיָה לָבֹא בְיִשְׂרָאֵל, אֵינוֹ רַשַּׁאי לְקַיְּמָהּ, שֶׁנֶּאֱמַר, (דברים כב) וְלוֹ תִהְיֶה לְאִשָּׁה, אִשָּׁה הָרְאוּיָה לוֹ:

How does one drink "in his earthen vessel"? Even if she were lame, or blind, or covered with [leprous] boils. If he found in her a thing of nakedness (i.e., indecency), or if she were not fit (halachically) to marry a Jew, he is not permitted to take her, it being written (Deuteronomy 22:29): "And to him shall she be as a wife" — one who is permitted to him as a wife.
