Leviticus 6:12-16

12Adonai spoke to Moses, saying:

13“This is the offering of Aaron and his sons, which they are to offer to Adonai on the day when he is anointed: the tenth part of an ephah of fine flour for a continual grain offering, half of it in the morning, and half of it in the evening.

14It is to be made with oil on a pan. When it is soaked, you shall bring it in. You are to present the grain offering in baked pieces as a soothing aroma to Adonai.

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.”
