Talmud for Shevuot 2:1
יְדִיעוֹת הַטֻּמְאָה שְׁתַּיִם שֶׁהֵן אַרְבַּע. נִטְמָא וְיָדַע וְנֶעֶלְמָה מִמֶּנּוּ הַטֻּמְאָה וְזָכוּר אֶת הַקֹּדֶשׁ, נֶעְלַם מִמֶּנּוּ הַקֹּדֶשׁ וְזָכוּר אֶת הַטֻּמְאָה, נֶעֶלְמוּ מִמֶּנּוּ זֶה וָזֶה וְאָכַל אֶת הַקֹּדֶשׁ וְלֹא יָדַע, וּמִשֶּׁאָכַל יָדַע, הֲרֵי זֶה בְעוֹלֶה וְיוֹרֵד. נִטְמָא וְיָדַע וְנֶעֶלְמָה מִמֶּנּוּ טֻמְאָה וְזָכוּר אֶת הַמִּקְדָּשׁ, נֶעְלַם מִמֶּנּוּ מִקְדָּשׁ וְזָכוּר אֶת הַטֻּמְאָה, נֶעֶלְמוּ מִמֶּנּוּ זֶה וָזֶה וְנִכְנַס לַמִּקְדָּשׁ וְלֹא יָדַע, וּמִשֶּׁיָּצָא יָדַע, הֲרֵי זֶה בְעוֹלֶה וְיוֹרֵד:
Awarenesses of uncleanliness are two, which are four. If he became unclean and knew [that he was unclean, at the time of contact or afterwards], and the uncleanliness was (afterwards) hidden from him, and he remembered the sanctity, [and because of that "hiddenness" (of the uncleanliness) he ate sanctified food — one; or entered the sanctuary — two. These are the two that are written. (Leviticus 5:2): "And it be hidden from him and he is unclean" implies that the uncleanliness is hidden from him. And because he is not liable unless he is aware in the beginning that he became unclean, after which it was hidden from him, we have "awarenesses."] If the sanctity were hidden from him [i.e., the fact of its being sanctified food or the fact of its being the sanctuary, and he ate the one or entered the other], and he remembered his uncleanliness [—These are the two others, which are not written.] If both were hidden from him and he ate sanctified food unawares, and after he ate he became aware, he is liable for an oleh veyored offering. [This is not part of the number. We are just being apprised that even though when he ate the sanctified food or entered the sanctuary he remembered neither the uncleanliness nor the sanctuary, he is liable for an oleh veyored offering.] If he became unclean and knew it, and the uncleanliness was hidden from him, and he remembered the sanctuary; if the sanctuary were hidden from him, and he remembered his uncleanliness; if both were hidden from him, and he entered the sanctuary unawares, and when he left he became aware, he is liable for an oleh veyored offering.
Jerusalem Talmud Horayot
For R. Simeon ben Laqish, the dedication of the sacrifice to atone for two infractions requires a new sacrifice for the third. For R. Joḥanan, the one sacrifice automatically is valid for the third also.] For Rebbi Joḥanan said, if part of the sin was atoned for, all of the sin was atoned for. Rebbi Simeon ben Laqish said, if part of the sin was atoned for, not all of the sin was atoned for.
