28 The Lord spoke to Moses, saying: 29 Speak to the people of Israel, saying: Any one of you who would offer to the Lord your sacrifice of well-being must yourself bring to the Lord your offering from your sacrifice of well-being. 30 Your own hands shall bring the Lord's offering by fire; you shall bring the fat with the breast, so that the breast may be raised as an elevation offering before the Lord. 31 The priest shall turn the fat into smoke on the altar, but the breast shall belong to Aaron and his sons. 32 And the right thigh from your sacrifices of well-being you shall give to the priest as an offering; 33 the one among the sons of Aaron who offers the blood and fat of the offering of well-being shall have the right thigh for a portion. 34 For I have taken the breast of the elevation offering, and the thigh that is offered, from the people of Israel, from their sacrifices of well-being, and have given them to Aaron the priest and to his sons, as a perpetual due from the people of Israel.

35 This is the portion allotted to Aaron and to his sons from the offerings made by fire to the Lord, once they have been brought forward to serve the Lord as priests; 36 these the Lord commanded to be given them, when he anointed them, as a perpetual due from the people of Israel throughout their generations. 37 This is the ritual of the burnt offering, the grain offering, the sin offering, the guilt offering, the offering of ordination, and the sacrifice of well-being, 38 which the Lord commanded Moses on Mount Sinai, when he commanded the people of Israel to bring their offerings to the Lord, 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!

Commentary on Leviticus 7:35-38

(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.
