Sforno on Leviticus 12:8/ספורנו על ויקרא י״ב:ח׳
אוְכִפֶּר עָלֶיהָ. כִּי כָּל יְמֵי זוֹב טֻמְאָתָהּ תִּהְיֶינָה כָּל מַחְשְׁבוֹתֶיהָ פּוֹנוֹת אֶל עִסְקֵי כְּלִי הַזֶּרַע וּפְעֻלָּתָם, וְלֹא תִהְיֶה רְאוּיָה לַמִּקְדָּשׁ וְקָדָשָׁיו עַד שֶׁתָּבִיא כַּפָּרָתָהּ וְתִפְנֶה אֶל הַקֹּדֶשׁ.
1וכפר עליה, for during all the days that she had been excreting blood her thoughts had been preoccupied with the phenomenon of semen, etc, and she had therefore not been in a fit state of mind to enter the precincts of the Temple and offer sacred matters.
