John Gill Commentary Deuteronomy 12:27

"and thou shalt offer thy burnt-offerings, the flesh and the blood, upon the altar of Jehovah thy God; and the blood of thy sacrifices shall be poured out upon the altar of Jehovah thy God; and thou shalt eat the flesh." — Deuteronomy 12:27 (ASV)

And you shall offer your burnt offerings, the flesh and the
blood, upon the altar of the Lord your God
And on that only, even the altar of burnt offering:

and the blood of your sacrifices ;
one as well as another, not only of the burnt offerings, but of the sin offerings, trespass offerings, and
peace offerings:

shall be poured out upon the altar of the Lord your God :
either sprinkled on it, or poured out at the bottom of it; see (Leviticus 1:1:17) (3:1-4:35) ,

and you shall eat the flesh ;
that is, of the peace offerings, for of them only might the people eat, and that only before the Lord.
