Sotah3: 3
עַד שֶׁלֹּא נִמְחֲקָה הַמְּגִלָּה אָמְרָה אֵינִי שׁוֹתָה — מְגִלָּתָהּ נִגְנֶזֶת, וּמִנְחָתָהּ מִתְפַּזֶּרֶת עַל הַדָּשֶׁן. וְאֵין מְגִלָּתָהּ כְּשֵׁרָה לְהַשְׁקוֹת בָּהּ סוֹטָה אַחֶרֶת. נִמְחֲקָה הַמְּגִלָּה וְאָמְרָה טְמֵאָה אָנִי — הַמַּיִם נִשְׁפָּכִין, וּמִנְחָתָהּ מִתְפַּזֶּרֶת עַל הַדָּשֶׁן. נִמְחֲקָה הַמְּגִלָּה וְאָמְרָה אֵינִי שׁוֹתָה — מְעַרְעֲרִים אוֹתָהּ וּמַשְׁקִין אוֹתָהּ בְּעַל כָּרְחָהּ.
Before the scroll was erased, [if] she said, “I will not drink,” her scroll is hidden away and her minchah-offering is scattered on the ash heap. Her scroll is not valid for the use of any other sotah. [If] the scroll was erased and she [then] said, “I am de-filed,” the water is poured out and her minchah-offering is scattered on the ash heap. [But if] the scroll was erased and she [then] said, “I will not drink,” they force her and make her drink against her will.
