20 but the soul that eateth of the flesh of the sacrifice of peace-offerings, that pertain unto Jehovah, having his uncleanness upon him, that soul shall be cut off from his people. 21 And when any one shall touch any unclean thing, the uncleanness of man, or an unclean beast, or any unclean abomination, and eat of the flesh of the sacrifice of peace-offerings, which pertain unto Jehovah, that soul shall be cut off from his people. 22 And Jehovah spake unto Moses, saying, 23 Speak unto the children of Israel, saying, Ye shall eat no fat, of ox, or sheep, or goat. 24 And the fat of that which dieth of itself, and the fat of that which is torn of beasts, may be used for any other service; but ye shall in no wise eat of it. 25 For whosoever eateth the fat of the beast, of which men offer an offering made by fire unto Jehovah, even the soul that eateth it shall be cut off from his people. 26 And ye shall eat no manner of blood, whether it be of bird or of beast, in any of your dwellings. 27 Whosoever it be that eateth any blood, that soul shall be cut off from his people. 28 And Jehovah spake unto Moses, saying, 29 Speak unto the children of Israel, saying, He that offereth the sacrifice of his peace-offerings unto Jehovah shall bring his oblation unto Jehovah out of the sacrifice of his peace-offerings: 30 his own hands shall bring the offerings of Jehovah made by fire; the fat with the breast shall he bring, that the breast may be waved for a wave-offering before Jehovah. 31 And the priest shall burn the fat upon the altar; but the breast shall be Aaron's and his sons'. 32 And the right thigh shall ye give unto the priest for a heave-offering out of the sacrifices of your peace-offerings. 33 He among the sons of Aaron that offereth the blood of the peace-offerings, and the fat, shall have the right thigh for a portion. 34 For the wave-breast and the heave-thigh have I taken of the children of Israel out of the sacrifices of their peace-offerings, and have given them unto Aaron the priest and unto his sons as [their] portion for ever from the children of Israel.

Matthew Henry's Commentary on Leviticus 7:20-34

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!
