Kesubos 1:9-2:2
Kesuvos1: 9
הָיְתָה מְעֻבֶּרֶת, וְאָמְרוּ לָהּ: ,,מַה טִּיבוֹ שֶׁל עֻבָּר זֶה”? ,,מֵאִישׁ פְּלוֹנִי, וְכֹהֵן הוּא” — רַבָּן גַּמְלִיאֵל וְרַבִּי אֱלִיעֶזֶר אוֹמְרִים: נֶאֱמֶנֶת. רַבִּי יְהוֹשֻׁעַ אוֹמֵר: לֹא מִפִּיהָ אָנוּ חַיִּין. אֶלָּא הֲרֵי זוֹ בְּחֶזְקַת מְעֻבֶּרֶת לְנָתִין וּלְמַמְזֵר, עַד שֶׁתָּבִיא רְאָיָה לִדְבָרֶיהָ.
[If a woman] was pregnant, and they said to her: “What is the nature of this fetus?” [and she replied: “He was fathered] by so-and-so, and he is a Kohen” —- Rabban Gamliel and R’ Eliezer say: She is believed. R’ Yehoshua [however] says: She is not be-lieved. Rather, it is presumed that she is pregnant from a Nesinite or a mamzer, until she proves her claim.
Kesuvos1: 10
אָמַר רַבִּי יוֹסֵי: מַעֲשֶׂה בְּתִינוֹקֶת שֶׁיָּרְדָה לְמַלּאוֹת מַיִם מִן הָעַיִן, וְנֶאֶנְסָה. אָמַר רַבִּי יוֹחָנָן בֶּן נוּרִי: אִם רֹב אַנְשֵׁי הָעִיר מַשִּׂיאִין לַכְּהֻנָּה — הֲרֵי זוֹ תִּנָּשֵׂא לַכְּהֻנָּה.
Said R’ Yose: [There was] an incident concerning a young girl who went down to draw water from a spring, and was violated. Said R’ Yochanan ben Nuri: If most men of the city may marry off [their daughters] to Kohanim, this one may marry a Kohen.
Kesuvos2: 1
הָאִשָּׁה שֶׁנִתְאַרְמְלָה אוֹ שֶׁנִּתְגָּרְשָׁה, הִיא אוֹמֶרֶת: ,,בְּתוּלָה נְשָׂאתַנִי”, וְהוּא אוֹמֵר: ,,לֹא כִי, אֶלָּא אַלְמָנָה נְשָׂאתִיךְ” — אִם יֵשׁ עֵדִים שֶׁיָּצָאת בְּהִינוּמָא וְרֹאשָׁהּ פָּרוּעַ — כְּתֻבָּתָהּ מָאתַיִם. רַבִּי יוֹחָנָן בֶּן בְּרוֹקָה אוֹמֵר: אַף חִלּוּק קְלָיוֹת רְאָיָה.
A woman who was widowed or divorced, [and] says: “You married me as a virgin,” and he says: “Not so, but I married you as a widow” —- if there are witnesses that she went out with a veil and with her hair untied, her kesubah is two hundred [zuz]. R’ Yochanan ben Berokah says: [The] distribution of parched grain is also proof.
Kesuvos2: 2
וּמוֹדֶה רַבִּי יְהוֹשֻׁעַ בְּאוֹמֵר לַחֲבֵרוֹ: ,,שָׂדֶה זוֹ שֶׁל אָבִיךָ הָיְתָה, וּלְקַחְתִּיהָ הֵימֶנּוּ”, שֶׁהוּא נֶאֱמָן, שֶׁהַפֶּה שֶׁאָסַר הוּא הַפֶּה שֶׁהִתִּיר. וְאִם יֵשׁ עֵדִים שֶׁהִיא שֶׁל אָבִיו, וְהוּא אוֹמֵר: ,,לְקַחְתִּיהָ הֵימֶנּוּ” — אֵינוֹ נֶאֱמָן.
And R’ Yehoshua admits [that] if one says to another: “This field was your father’s, and I bought it from him,” that he is believed, for the one that created the liability is the one that undid it. If, however, there are witnesses that it was his father’s, and he says: “I bought it from him,” he is not believed.
