Leviticus 6:16, 18, 20, 26

Aaron and his sons may eat the rest of the flour, but it must be baked without yeast and eaten in a sacred place within the courtyard of the Tabernacle.

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.”

“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.

The priest who offers the sacrifice as a sin offering must eat his portion in a sacred place within the courtyard of the Tabernacle.
