Exodus 29:31

It shall be for Aaron and his sons as their portion forever from the children of Israel; for it is a wave offering. It shall be a wave offering from the children of Israel of the sacrifices of their peace offerings, even their wave offering to the LORD.

“The holy garments of Aaron shall be for his sons after him, to be anointed in them, and to be consecrated in them.

Seven days shall the son who is priest in his place put them on, when he comes into the Tent of Meeting to minister in the holy place.

Aaron and his sons shall eat the meat of the ram, and the bread that is in the basket, at the door of the Tent of Meeting.

They shall eat those things with which atonement was made, to consecrate and sanctify them; but a stranger shall not eat of it, because they are holy.

If anything of the meat of the consecration, or of the bread, remains to the morning, then you shall burn the remainder with fire. It shall not be eaten, because it is holy.
