20 but the soul who eats of the flesh of the sacrifice of peace offerings, that belongs to Yahweh, having his uncleanness on him, that soul shall be cut off from his people. 21 When anyone touches any unclean thing, the uncleanness of man, or an unclean animal, or any unclean abomination, and eats some of the flesh of the sacrifice of peace offerings, which belong to Yahweh, that soul shall be cut off from his people.’” 22 Yahweh spoke to Moses, saying, 23 “Speak to the children of Israel, saying, ‘You shall eat no fat, of bull, or sheep, or goat. 24 The fat of that which dies of itself, and the fat of that which is torn of animals, may be used for any other service, but you shall in no way eat of it. 25 For whoever eats the fat of the animal, of which men offer an offering made by fire to Yahweh, even the soul who eats it shall be cut off from his people. 26 You shall not eat any blood, whether it is of bird or of animal, in any of your dwellings. 27 Whoever it is who eats any blood, that soul shall be cut off from his people.’” 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.’”

Commentary on Leviticus 7:11-27

(Read Leviticus 7:11-27)

As to the peace-offerings, in the expression of their sense of mercy, God left them more at liberty, than in the expression of their sense of sin; that their sacrifices, being free-will offerings, might be the more acceptable, while, by obliging them to bring the sacrifices of atonement, God shows the necessity of the great Propitiation. The main reason why blood was forbidden of old, was because the Lord had appointed blood for an atonement. This use, being figurative, had its end in Christ, who by his death and blood-shedding caused the sacrifices to cease. Therefore this law is not now in force on believers.

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!
