ואם האכל יאכל וגו'. בִּמְחַשֵּׁב בַּשְּׁחִיטָה לְאָכְלוֹ בַּשְּׁלִישִׁי הַכָּתוּב מְדַבֵּר; יָכוֹל אִם אָכַל מִמֶּנּוּ בַּשְּׁלִישִׁי יִפָּסֵל לְמַפְרֵעַ, תַּלְמוּד לוֹמַר הַמַּקְרִיב אֹתוֹ לֹא יֵחָשֵׁב — בִּשְׁעַת הַקְרָבָה הוּא נִפְסָל וְאֵינוֹ נִפְסָל בַּשְּׁלִישִׁי; וְכֵן פֵּרוּשׁוֹ: בִּשְׁעַת הַקְרָבָתוֹ לֹא תַּעֲלֶה זֹאת בְּמַחֲשָׁבָה, וְאִם חִשֵּׁב פִּגּוּל יִהְיֶה (זבחים כ"ט): אם האכל יאכל וגו' AND IF ANY [OF THE FLESH] SHOULD BE EATEN AT ALL [ON THE THIRD DAY) — Scripture is speaking of one who has the intention whilst slaughtering thė sacrifice to eat it (the flesh) on the third day. One might think that what the text really means is, that if one has eaten of it on the third day it becomes disqualified retrospectively (i. e., that it is regarded as having been invalid from the moment that it was offered)! Scripture, however, states, “As for him that offereth it, there shall be no מחשבה to him” implying that at the time when it is offered it can become disqualified, and that it cannot become disqualified on the third day (Sifra, Tzav, Section 8 1). And the following is its meaning (that of the text): At the time when it is offered, this shall not enter the mind of any priest performing a rite with it, to eat of it on the third day, and if he does harbour such a thought, it becomes פגול, an abominable thing,
והנפש האכלת ממנו. אֲפִלּוּ בְּתוֹךְ הַזְּמַן עונה תשא: והנפש האכלת ממנו AND THE SOUL THAT EATETH OF IT even within this period (of three days), עונה תשא SHALL BEAR ITS INIQUITY.
