Leviticus 7:29-32

29Speak unto the children of Israel, saying, He that presenteth the sacrifice of his peace-offering to Jehovah shall bring his offering to Jehovah of the sacrifice of his peace-offering.

30His own hands shall bring Jehovah's offerings by fire, the fat with the breast shall he bring: the breast, that it may be waved as a wave-offering before Jehovah.

31And the priest shall burn the fat on the altar; and the breast shall be Aaron's and his sons'.

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