Halakhah su Deuteronomio 12:27

From the laws of the commandment is that which they, may their memory be blessed, said about the procedure of the burnt-offering that it was executed thus: We slaughter the beast in the [Temple] yard - and the slaughter is fit even with non-priests, but from the reception of the blood and onward, it is a commandment of the priesthood. And the priest would sprinkle the blood and flay it and dissect the limbs whole - as it is written (Leviticus 1:6), "into sections," and they, may their memory be blessed, explained (Chullin 11:1), "And not sections into sections." And when he dissects [it], he removes the sciatic nerve from the thigh, and incinerates all of the sections on top of the altar. And the wool on the heads of the sheep, the hair of the beards of the male goats, the bones, the tendons, the horns and the hooves - when they are attached - we incinerate it all, as it is stated (Leviticus 1:9), "and the priest incinerates it all." [But if] they were separated, they do not go up, as it is stated (Deuteronomy 12:26), "And you shall execute your burnt-offerings, the meat and the blood."

But Ramban, may his memory be blessed, wrote (Sefer HaMitzvot, Mitzvot Ase 85) there is only one commandment with all of the consecrated [animals], whether consecrated [animals from] the Land or whether those [from] outside of the Land; and that we should not make them two commandments. And even though it is true that is expounded in Sifrei to be about the consecrated [animals from] outside of the Land, this is not truly a proof to make them two commandments. And in the third chapter of Tractate Temurah 17b they expounded it in a different way. As there they said, "'But your consecrated things' - these are the exchanged animals; 'that shall be for you' - these are the offspring; 'and your vows' - that is a vow; 'shall you carry and come' - it is possible that they bring them to the Choice House and prevent water and food from them such that they die; [hence] we learn to say, 'And you shall effect your burnt-offering, the meat and the blood' (Deuteronomy 12:27) - in the way that you act with the burnt-offering, so should you act with the exchanged animal, and in the way that you act with the peace-offerings, so should you act with the offspring of the peace-offerings and the animals exchanged for them." The whole content of this commandment is like the content of the third commandment in this Order (Sefer HaChinukh 440) and there is one root to both of them. [Hence] there is no need to be lengthy of speech about it.
