הלכה על מכות 33:16

To not eat higher-level consecrated foods (kodshai kodashim) outside of the [Temple] yard: To not eat - and even priests - from the meat of the sin-offering, and the guilt-offering outside of the 'curtains.' And the masters of the tradition explained that this prohibition is included in "You may not eat in your gates, etc. your cattle and your flocks" (Deuteronomy 12:17). As so did they, may their memory be blessed, say (Makkot 17a), "The verse only comes with regard to one who eats a sin-offering or a guilt-offering[...] outside the curtains, [to teach that he is transgressing a negative commandment]." And so too, one who eats lower-level consecrated foods (kodashim kalim) outside of the wall [of Jerusalem] is included in this prohibition, like the Gemara comes to teach. As they said there that anyone who eats something outside the place of its eating is [considered], "You may not eat in your gates." And their intention, may their memory be blessed, in saying, "The verse only comes," is to say that this is also included.
