8לֹא בְּכָל מָקוֹם שֶׁנִּמְצָא הַדָּם עַל בְּשָׂרָהּ תִּטְמָא מִשּׁוּם כֶּתֶם עַד שֶׁיִּמָּצֵא כְּנֶגֶד בֵּית הַתֻּרְפָּה. כֵּיצַד. נִמְצָא עַל עֲקֵבָהּ טְמֵאָה שֶׁמָּא נָגַע בְּבֵית תֻּרְפָּה בְּעֵת יְשִׁיבָתָהּ. וְכֵן אִם נִמְצָא עַל שׁוֹקָהּ אוֹ עַל פַּרְסוֹתֶיהָ מִבִּפְנִים וְהֵם הַמְּקוֹמוֹת הַנִּדְבָּקוֹת זוֹ בְּזוֹ בְּעֵת שֶׁתַּעֲמֹד וְתִדְבֹּק רֶגֶל לְרֶגֶל וְשׁוֹק לְשׁוֹק הֲרֵי זוֹ טְמֵאָה. נִמְצָא עַל רֹאשׁ גּוּדַל רַגְלָהּ טְמֵאָה שֶׁמָּא נָטַף מִן הַחֶדֶר עַל רַגְלָהּ בְּעֵת שֶׁהָלְכָה. וְכֵן כָּל מָקוֹם שֶׁאֶפְשָׁר שֶׁיִּנָּתֵז עָלָיו דַּם נִדָּתָהּ כְּשֶׁתְּהַלֵּךְ וְנִמְצָא שָׁם דָּם טְמֵאָה. וְכֵן אִם נִמְצָא הַדָּם עַל יָדֶיהָ אֲפִלּוּ עַל קִשְׁרֵי אֶצְבְּעוֹת יָדֶיהָ טְמֵאָה שֶׁהַיָּדַיִם עַסְקָנִיּוֹת הֵן. אֲבָל אִם נִמְצָא הַדָּם עַל שׁוֹקָהּ וְעַל פַּרְסוֹתֶיהָ מִבַּחוּץ אוֹ מִן הַצְּדָדִין וְאֵין צָרִיךְ לוֹמַר אִם נִמְצָא מִן הַיְרֵכַיִם וּלְמַעְלָה הֲרֵי זוֹ טְהוֹרָה שֶׁאֵין זֶה אֶלָּא דָּם שֶׁנִּתַּז עָלֶיהָ מִמָּקוֹם אַחֵר:
[A woman] does not become impure because of a bloodstain found on every place on her body, only due to those found opposite her genital area. What is implied? If a stain is found on her heel, she is impure. For perhaps she touched her genital area when she sat. Similarly, she is impure if a stain was found on her calves or on the inner side of her ankles, [the portions of her legs] that will touch each other when she stands with her feet and calves together. If it is found on the tip of her toe, she is impure. Perhaps [blood] dripped from the uterus to her foot when she walked. Similarly, if blood is found in any place where her menstrual blood could have spattered when she walked, she is impure. Similarly, if blood is found on her hands, even on the backs of her fingers, she is impure. For the hands are active. If, however, blood is found on the outer or side portions of her calves and, needless to say, if it is found from her thighs upward, she is pure. For this is certainly blood that was spattered on her from another place.
