26. And you shall not eat any blood in any of your dwelling places, whether from birds or from animals.
Rashi: [And you shall not eat any blood…] whether from birds or from animals: Excluded [from this prohibition is] the blood of fish and locusts. — [Torath Kohanim 7:143]
in any of your dwelling places: Since this prohibition [of eating blood] is an obligation relevant to a person, rather than being dependent on land, it applies to all dwelling places [of the Jews, whether in Israel or outside of it]. [But one might think it obvious that since it is a personal obligation, it would apply anywhere, as is indeed the rule. So why should it be stated here?] In Tractate Kiddushin, chapter one (37b), it is explained why this is necessary to be stated.
27. Any person who eats any blood, that soul shall be cut off from its people.
