Halakhah zu Dewarim 12:12

That is that He commanded us to offer all of the sacrifices in the [Temple]. And that is His, may He be exalted, saying, "there you shall bring up your burnt-offerings and there you shall do" (Deuteronomy 12:14). And because they wanted to confirm the prohibition not to offer any of all the sacrifices outside [of it], they took the proof from His saying, "lest you bring up your burnt-offerings [in any place]" (Deuteronomy 12:12). And they said in the Sifrei (Sifrei Devarim 70:5-6), "This tells me only of burnt-offerings. From where [do we know the same is true for] other offerings? [Hence] we learn to say, 'and there you shall do all that I command you' (Deuteronomy 12:14). But I still would say that only burnt-offerings are subject to a positive and a negative commandment. From where [do we know the same is true for] other offerings? [Hence] we learn to say, 'and there you shall do'" - as we will explain in its place, when we speak about the prohibition (Sefer HaMitzvot, Negative Commandments 89). And the content of their saying, "burnt-offerings are subject to a positive commandment and a negative commandment," is that one who offers a burnt-offering outside would be transgressing a positive and a negative commandment. Indeed, the negative commandment is His saying, "lest you bring up your burnt-offerings"; and for the positive commandment, it is His saying, "there you shall bring up." [And their saying,] "Other offerings would only be a positive commandment," is meaning to say, His saying, "and there you shall do," by itself. But it is explained that even for other offerings, one also transgresses a negative commandment, along with a positive commandment. And it has already been explained at the end of Zevachim (Zevachim 119b) that all offerings that are sacrificed outside [are a violation of] a positive and a negative commandment, and one is liable excision on their account. Behold it has been made clear to you from all that I said that His saying, "and there you shall do," is a full-fledged positive commandment.
