Leviticus 10:11

Then the LORD said to Aaron,

“You and your sons are not to drink wine or strong drink whenever you go into the Tent of Meeting, or you will die. This shall be a statute forever throughout your generations.

You are to make a distinction between the holy and the common, and between the unclean and the clean.

Moses spoke to Aaron, and to Eleazar and to Ithamar, his sons who were left, “Take the meal offering that remains of the offerings of the LORD made by fire, and eat it without yeast beside the altar; for it is most holy;

and you shall eat it in a holy place, because it is your portion, and your sons’ portion, of the offerings of the LORD made by fire; for so I am commanded.

The waved breast and the heaved thigh you shall eat in a clean place, you, and your sons, and your daughters with you: for they are given as your portion, and your sons’ portion, out of the sacrifices of the peace offerings of the children of Israel.
