Leviticus 6:17-23

Remember, it must never be prepared with yeast. I have given it to the priests as their share of the special gifts presented to me. Like the sin offering and the guilt offering, it is most holy. Any of Aaron’s male descendants may eat from the special gifts presented to the LORD. This is their permanent right from generation to generation. Anyone or anything that touches these offerings will become holy.” Then the LORD said to Moses, “On the day Aaron and his sons are anointed, they must present to the LORD the standard grain offering of two quarts of choice flour, half to be offered in the morning and half to be offered in the evening. It must be carefully mixed with olive oil and cooked on a griddle. Then slice this grain offering and present it as a pleasing aroma to the LORD. In each generation, the high priest who succeeds Aaron must prepare this same offering. It belongs to the LORD and must be burned up completely. This is a permanent law. All such grain offerings of a priest must be burned up entirely. None of it may be eaten.”
