And the flesh of them shall be thine, as the wave breast and as the right shoulder are thine.
Exodus 29:26-28
26
And thou shalt take the breast of the ram of Aaron's consecration, and wave it for a wave offering before the LORD: and it shall be thy part.
27
And thou shalt sanctify the breast of the wave offering, and the shoulder of the heave offering, which is waved, and which is heaved up, of the ram of the consecration, even of that which is for Aaron, and of that which is for his sons:
28
And it shall be Aaron's and his sons' by a statute for ever from the children of Israel: for it is an heave offering: and it shall be an heave offering from the children of Israel of the sacrifice of their peace offerings, even their heave offering unto the LORD.
Leviticus 7:31-34
31
And the priest shall burn the fat upon the altar: but the breast shall be Aaron's and his sons'.
32
And the right shoulder shall ye give unto the priest for an heave offering of the sacrifices of your peace offerings.
33
He among the sons of Aaron, that offereth the blood of the peace offerings, and the fat, shall have the right shoulder for his part.
34
For the wave breast and the heave shoulder have I taken of the children of Israel from off the sacrifices of their peace offerings, and have given them unto Aaron the priest and unto his sons by a statute for ever from among the children of Israel.
