Kesuvos2: 5
הָאִשָּׁה שֶׁאָמְרָה: ,,אֵשֶׁת אִישׁ הָיִיתִי, וּגְרוּשָׁה אֲנִי” — נֶאֱמֶנֶת, שֶׁהַפֶּה שֶׁאָסַר הוּא הַפֶּה שֶׁהִתִּיר. וְאִם יֵשׁ עֵדִים שֶׁהָיְתָה אֵשֶׁת אִישׁ, וְהִיא אוֹמֶרֶת: ,,גְּרוּשָׁה אֲנִי” — אֵינָהּ נֶאֱמֶנֶת.  אָמְרָה: ,,נִשְׁבֵּיתִי, וּטְהוֹרָה אֲנִי” — נֶאֱמֶנֶת, שֶׁהַפֶּה שֶׁאָסַר הוּא הַפֶּה שֶׁהִתִּיר. וְאִם יֵשׁ עֵדִים שֶׁנִּשְׁבֵּית, וְהִיא אוֹמֶרֶת: ,,טְהוֹרָה אֲנִי” — אֵינָהּ נֶאֱמֶנֶת. וְאִם מִשֶּׁנִּשֵּׂאת בָּאוּ עֵדִים — הֲרֵי זוֹ לֹא תֵצֵא.
[If] a woman said: “I was married, but I am divorced,” she is believed, for the one that created the liability is the one that undid it. If, however, there are witnesses that she was married, and she says: “I am divorced,” she is not believed.  [If] she said: “I was captured, but I am undefiled,” she is believed, for the one that created the liability is the one that undid it. If there are wit-nesses that she was captured, however, and she says: “I am undefiled,” she is not believed. But, if after she married, witnesses came, she need not leave.
