Leviticus 7:31KJV

29Speak unto the children of Israel, saying, He that offereth the sacrifice of his peace offerings unto the LORD shall bring his oblation unto the LORD of the sacrifice of his peace offerings.

30His own hands shall bring the offerings of the LORD made by fire, the fat with the breast, it shall he bring, that the breast may be waved a wave offering before the LORD.

31And the priest shall burn the fat upon the altar: but the breast shall be Aaron's and his sons'.

32And the right shoulder shall ye give unto the priest an heave offering of the sacrifices of your peace offerings.

33He among the sons of Aaron, that offereth the blood of the peace offerings, and the fat, shall have the right shoulder for part.
