28 God spoke to Moses, 29 "Speak to the People of Israel. Tell them: When you present a Peace-Offering to God, bring some of your Peace-Offering as a special sacrifice to God, 30 a gift to God in your own hands. Bring the fat with the breast and then wave the breast before God as a Wave-Offering. 31 The priest will burn the fat on the Altar; Aaron and his sons get the breast. 32 Give the right thigh from your Peace-Offerings as a Contribution-Offering to the priest. 33 Give a portion of the right thigh to the son of Aaron who offers the blood and fat of the Peace-Offering as his portion. 34 From the Peace-Offerings of Israel, I'm giving the breast of the Wave-Offering and the thigh of the Contribution-Offering to Aaron the priest and his sons. This is their fixed compensation from the People of Israel."

35 From the day they are presented to serve as priests to God, Aaron and his sons can expect to receive these allotments from the gifts of God. 36 This is what God commanded the People of Israel to give the priests from the day of their anointing. This is the fixed rule down through the generations. 37 These are the instructions for the Whole-Burnt-Offering, the Grain-Offering, the Absolution-Offering, the Compensation-Offering, the Ordination-Offering, and the Peace-Offering 38 which God gave Moses at Mount Sinai on the day he commanded the People of Israel to present their offerings to God in the wilderness of Sinai.

Commentary on Leviticus 7:28-34

(Read Leviticus 7:28-34)

The priest who offered, was to have the breast and the right shoulder. When the sacrifice was killed, the offerer himself must present God's part of it; that he might signify his cheerfully giving it up to God. He was with his own hands to lift it up, in token of his regard to God as the God of heaven; and then to wave it to and fro, in token of his regard to God as the Lord of the whole earth. Be persuaded and encouraged to feed and feast upon Christ, our Peace-offering. This blessed Peace-offering is not for the priests only, for saints of the highest rank and greatest eminence, but for the common people also. Take heed of delay. Many think to repent and return to God when they are dying and dropping into hell; but they should eat the peace-offering, and eat it now. Stay not till the day of the Lord's patience be run out, for eating the third day will not be accepted, nor will catching at Christ when thou art gone to hell!

(Read Leviticus 7:35-38)

Solemn acts of religious worship are not things which we may do or not do at our pleasure; it is at our peril if we omit them. An observance of the laws of Christ cannot be less necessary than of the laws of Moses.
