Leviticus 7:28-36 - Portions Of Fellowship Offerings For Priests
28 And the LORD talked with Moses, saying, 29 "Speak unto the children of Israel and say, 'He that offereth his peace offering unto the LORD, shall bring his gift unto the LORD of his peace offerings: 30 his own hands shall bring the offering of the LORD; even the fat upon the breast he shall bring with the breast to wave it a wave offering before the LORD. 31 And the priest shall burn the fat upon the altar, and the breast shall be Aaron's and his sons. 32 And the right shoulder they shall give unto the priest, to be a heave offering, of their peace offerings. 33 And the same that offereth the blood of the peace offerings and the fat, among the sons of Aaron, shall have the right shoulder unto his part, 34 for the wavebreast and the heaveshoulder I have taken of the children of Israel, even of their peace offerings, and have given it unto Aaron the priest and unto his sons: to be a duty forever of the children of Israel."
35 This is the anointing of Aaron and of the sacrifices of the LORD, in the day when they were offered to be priests unto the LORD, 36 which the LORD commanded to be given them in the day when he anointed them, of the children of Israel, and to be a duty for ever among their generations.
