Leviticus 6:15-18

15The anointed kohen who will be in his place from among his sons is to offer it. As an eternal statute, it must be entirely burnt up as smoke to Adonai.

16Thus every grain offering of a kohen is to be a whole-offering—it shall not be eaten.”

17Adonai spoke to Moses, saying:

18“Speak to Aaron and to his sons, saying: ‘This is the Torah of the sin offering. In the place where the burnt offering is slaughtered, the sin ­offering is to be slaughtered before Adonai. It is most holy.
