Jerusalem Talmud Nedarim 11:10

משנה: תֵּשַׁע נְעָרוֹת נִדְרֵיהֶן קַייָמִין. בּוֹגֶרֶת וְהִיא יְתוֹמָה נַעֲרָה וּבָֽגְרָה וְהִיא יְתוֹמָה נַעֲרָה שֶׁלֹּאֹ בָֽגְרָה וְהִיא יְתוֹמָה. בּוֹגֶרֶת וּמֵת אָבִיהָ נַעֲרָה בוֹגָרֶת וּמֵת אָבִיהָ נַעֲרָה שֶׁלֹּא בָֽגְרָה וּמֵת אָבִיהָ. נַעֲרָה שֶׁמֵּת אָבִיהָ וּמִשֶּׁמֵּת אָבִיהָ בָֽגְרָה בּוֹגֶרֶת וְאָבִיהָ קַייָם נַעֲרָה בוֹגֶרֶת וְאָבִיהָ קַייָם. רִבִּי יְהוּדָה אוֹמֵר. אַף הַמַּשִּׂיא בִתּוֹ הַקְּטַנָּה וְנִתְאַלְמְנָה אוֹ נִתְגָּֽרְשָׁה וְחָֽזְרָה אֶצְלוֹ עֲדַיִן הִיא נַעֲרָה. MISHNAH: The vows of nine young women⁷⁶In this introduction to the Mishnah, נערה is used in a nontechnical term “young female”, whether minor, adolescent, or of age. Later the same word is used in a more technical sense, “underage or adolescent.” The principle underlying the Mishnah is very simple: The vows of an unmarried girl are not subject to dissolution if either she has no father or she is emancipated from him either by coming of age or by having been definitively married and then divorced or widowed. are confirmed: An adult who is an orphan, an adolescent who became an adult and is an orphan, an adolescent who did not become an adult but is an orphan. An adult whose father died, an adolescent who became an adult and her father died, an adolescent who did not become an adult and her father died. An adolescent whose father died and afterwards she became an adult, an adult whose father lives, an adolescent girl whose father lives. Rebbi Jehudah says, also if somebody marries off his underage daughter and she becomes widowed or divorced and returns to him, she still is an adolescent⁷⁷R. Jehudah denies that an underage girl (not an adolescent) is emancipated from her father by marriage..

הלכה: תֵּשַׁע נְעָרוֹת נִדְרֵיהֶן קַייָמִין כול׳. אָמַר רִבִּי יוֹחָנָן. שְׁתַּיִם הֵן. וְלָמָּה תַנִּינָן תֵּשַׁע. בִּשְׁבִיל לְחַדֵּד אֶת הַתַּלְמִידִים. וּכְרִבִּי יוּדָה שָׁלֹשׁ. HALAKHAH: “The vows of nine young women are confirmed,” etc. Rebbi Joḥanan said, there are two⁷⁸One category is the orphan and the minor or adolescent emancipated by dissolution of her marriage; the other is the adult. For R. Jehudah, the widowed or divorced minor falls in a separate category. The Babli, 89b, holds that the nine are R. Jehudah’s but that the majority recognizes the adult, the orphan, and the minor or adolescent emancipated by dissolution of her marriage.. But why did we state “two”? To train the students. And according to Rebbi Jehudah, there are three.
