Reference for Sotah 2:5
עַל מַה הִיא אוֹמֶרֶת אָמֵן אָמֵן. אָמֵן עַל הָאָלָה, אָמֵן עַל הַשְּׁבוּעָה. אָמֵן מֵאִישׁ זֶה, אָמֵן מֵאִישׁ אַחֵר. אָמֵן שֶׁלֹּא שָׂטִיתִי אֲרוּסָה וּנְשׂוּאָה וְשׁוֹמֶרֶת יָבָם וּכְנוּסָה, אָמֵן שֶׁלֹּא נִטְמֵאתִי. וְאִם נִטְמֵאתִי, יָבֹאוּ בִי. רַבִּי מֵאִיר אוֹמֵר, אָמֵן שֶׁלֹּא נִטְמֵאתִי, אָמֵן שֶׁלֹּא אֶטָּמֵא:
To what does she respond 'Amen Amen'? Amen to the curse, Amen to the oath. Amen with regard to this man, Amen with regard to another man. Amen that I did not commit adultery while betrothed, or while married, or while awaiting Levirate marriage, or after being taken [to his house]. Amen that I did not become impure. And if I became impure, may they [the curses] be upon me. R. Meir said: Amen that I did not become impure, Amen that I will not become impure.
