11 "And this is the law of the sacrifice of peace offerings which one may offer to the Lord. 12 If he offers it for a thanksgiving, then he shall offer with the thank offering unleavened cakes mixed with oil, unleavened wafers spread with oil, and cakes of fine flour well mixed with oil. 13 With the sacrifice of his peace offerings for thanksgiving he shall bring his offering with cakes of leavened bread. 14 And of such he shall offer one cake from each offering, as an offering to the Lord; it shall belong to the priest who throws the blood of the peace offerings. 15 And the flesh of the sacrifice of his peace offerings for thanksgiving shall be eaten on the day of his offering; he shall not leave any of it until the morning. 16 But if the sacrifice of his offering is a votive offering or a freewill offering, it shall be eaten on the day that he offers his sacrifice, and on the morrow what remains of it shall be eaten, 17 but what remains of the flesh of the sacrifice on the third day shall be burned with fire.
Matthew Henry's Commentary on Leviticus 7:11-17
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.
