Commentary for Deuteronomy 12:25

לא תאכלנו THOU SHALT NOT EAT IT — This is a prohibition against eating of the blood contained in the limbs (Keritot 4b).

'לא תאכלנו....כי.תעשה הישר בעיני ה, when you refrain from eating it this shall not be because you despise it, i.e. it repels you; you must not eat it in order to thereby do what is right in the eyes of the Lord. Our sages in Torat Kohanim on Kedoshim 9,10 phrase it thus: “one must not say: ‘I am revolted by pig’s meat,’ but one should say: ‘I am perfectly capable of enjoying pig’s meat; the only reason I do not is in order to comply with G’d’s prohibition of it.’”

This prohibits the blood absorbed in the limbs. Rashi’s explanation poses a difficulty, for in chapter “Kol Habasar” (Chulin 115b), this verse, “Do not eat it,” is understood to prohibit [the combination of] meat and milk. And [furthermore,] Rashi himself explains likewise in the first chapter of Krisus (4b). Re”m also raises this difficulty. However, it seems to me: Rashi’s explanation here follows the viewpoint of the other Tannaim and Amoraim in chapter “Kol Habasar.” And they learn out the prohibition not to eat meat and milk from other verses (see there). One Tanna learns out [the prohibition not to eat meat and milk] from the verse, ‘Do not cook a kid in its mother’s milk,’ which is written three times, and one of them is intended to prohibit eating [them together].” See Rashi above in Parshas Mishpatim (Shmos 23:19). But Rashi’s explains in Krisus follows the viewpoint of Rebbi who explains that, “Do not eat it,” is a prohibition not to eat meat and milk.
