Jerusalem Talmud Yevamot 11.3

משנה: חָמֵשׁ נָשִׁים שֶׁנִּתְעָרְבוּ וַולְדוֹתֵיהֶן הִגְדִּילוּ הַתַּעֲרוֹבוֹת וְנָשְׂאוֹ נָשִׁים וָמֵתוּ אַרְבָּעָה חוֹלְצִין לְאַחַת וְאֶחָד מְיַיבֵּם אוֹתָהּ. הוּא וּשְׁלֹשָׁה חוֹלְצִים לְאַחֶרֶת וְאֶחָד מְיַיבֵּם. נִמְצְאוּ אַרְבַּע חֲלִיצוֹת וְיִיבּוּם לְכָל אַחַת וְאַחַת.

MISHNAH: If the children of five women were mixed up, and the mixed-up became adults, married wives, and died, then four perform ḥalîṣah and one marries in levirate. This one and three others perform ḥalîṣah for another one and another one marries in levirate. It turns out that there are four ḥaliṣot and one levirate marriage for every one.

הלכה: חָמֵשׁ נָשִׁים שֶׁנִּתְעָרְבוּ וַולְדוֹתֵיהֶן כול׳. בְּכָל אָתָר אַתְּ אָמַר. אֵין חֲלִיצָה אַחַר חֲלִיצָה. וְהָכָא אַתְּ אָמַר הָכֵין. כָּאן בְּוַדַּאי כָּאן בְּסָפֵק. בְּכָל אָתָר אַתְּ אָמַר. בְּכָל מָקוֹם שֶׁאֵין אוֹמְרִים. יַיבֵּם. אֵין אוֹמְרִים. חֲלוֹץ. וְהָכָא אַתְּ אָמַר אָכֵין. כָּאן בְּוַדַּאי כָּאן בְּסָפֵק.

HALAKHAH: “If the children of five women were mixed up,” etc. Everywhere you say, there is no ḥalîṣah after ḥalîṣah, and here, you say so? There, it is was sure, here it is in doubt. Everywhere you say, if one does not say to him, take in levirate, one does not say, perform ḥalîṣah, and here, you say so? There, it is was sure, here it is doubtful.
