Jerusalem Talmud Yevamot 14.5

משנה: שְׁנֵי אַחִין אֶחָד חֵרֵשׁ וְאֶחָד פִּיקֵּחַ נְשׂוּאִין לִשְׁתֵּי אֲחָיוֹת אַחַת חֵרֶשֶׁת וְאַחַת פִּיקַּחַת מֵת חֵרֵשׁ בַּעַל הַחֵרֶשֶׁת מַה יַעֲשֶׂה פִּקֵּחַ בַּעַל הַפִּיקַּחַת תֵּצֵא מְשּׁוּם אֲחוֹת אִשָּׁה. מֵת פִּקֵּחַ בַּעַל הַפִּיקַּחַת מַה יַעֲשֶׂה חֵרֵשׁ בַּעַל הַחֵרֶשֶׁת מוֹצִיא אִשְׁתּוֹ בְגֵט וְאֶשֶׁת אָחִיו אֲסוּרָה לְעוֹלָם.

MISHNAH: Two brothers, one deaf-mute and one hearing, married to two sisters, one deaf-mute and one hearing. If the deaf-mute [brother] married to the deaf-mute wife died, what shall the hearing [brother] married to a hearing wife do? [The widow] has to leave as the wife’s sister. If the hearing [brother] married to the hearing wife died, what shall the deaf-mute [brother] married to the deaf-mute wife do? He removes his wife by a bill of divorce; his brother’s wife is permanently forbidden.

הלכה: שְׁנֵי אַחִין אֶחָד חֵרֵשׁ כול׳. צָרָתָהּ מָהוּ. נִישְׁמְעִינָהּ מִן הָדָא. בִּתּוֹ חֵרֶשֶׁת נְשׂוּאָה לְאָחִיו חֵרֵשׁ. צָרָתָהּ פְטוּרָה מִן הַחֲלִיצָה וּמִן הַיִיבּוּם.

HALAKHAH: “Two deaf-mute brothers,” etc. What about her co-wife? Let us hear from the following: If his deaf-mute daughter was married to his deaf-mute brother, her co-wife is free from ḥalîṣah and levirate.
