Deuteronomy 12:27

And thou shalt offer thy burnt offerings, the flesh and the
blood, upon the altar of the Lord thy God
And on that only, even the altar of burnt offering:

and the blood of thy 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 thy God:
either sprinkled on it, or poured out at the bottom of it; see ( Leviticus 1:1-1:17 ) ( 3:1-4:35 ) ,

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