28 Yahweh spoke to Moses, saying, 29 “Speak to the children of Israel, saying, ‘He who offers the sacrifice of his peace offerings to Yahweh shall bring his offering to Yahweh out of the sacrifice of his peace offerings. 30 With his own hands he shall bring the offerings of Yahweh made by fire. He shall bring the fat with the breast, that the breast may be waved for a wave offering before Yahweh. 31 The priest shall burn the fat on the altar, but the breast shall be Aaron’s and his sons’. 32 The right thigh you shall give to the priest for a heave offering out of the sacrifices of your peace offerings. 33 He among the sons of Aaron who offers the blood of the peace offerings, and the fat, shall have the right thigh for a portion. 34 For the waved breast and the heaved thigh I have taken from the children of Israel out of the sacrifices of their peace offerings, and have given them to Aaron the priest and to his sons as their portion forever from the children of Israel.’”

35 This is the anointing portion of Aaron, and the anointing portion of his sons, out of the offerings of Yahweh made by fire, in the day when he presented them to minister to Yahweh in the priest’s office; 36 which Yahweh commanded to be given them of the children of Israel, in the day that he anointed them. It is their portion forever throughout their generations. 37 This is the law of the burnt offering, of the meal offering, and of the sin offering, and of the trespass offering, and of the consecration, and of the sacrifice of peace offerings; 38 which Yahweh commanded Moses in Mount Sinai, in the day that he commanded the children of Israel to offer their offerings to Yahweh, 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!

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.
