11 And this is the law of the sacrifice of peace-offerings, which one shall offer unto Jehovah. 12 If he offer it for a thanksgiving, then he shall offer with the sacrifice of thanksgiving unleavened cakes mingled with oil, and unleavened wafers anointed with oil, and cakes mingled with oil, of fine flour soaked. 13 With cakes of leavened bread he shall offer his oblation with the sacrifice of his peace-offerings for thanksgiving. 14 And of it he shall offer one out of each oblation for a heave-offering unto Jehovah; it shall be the priest's that sprinkleth 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 oblation; he shall not leave any of it until the morning.
Matthew Henry's Commentary on Leviticus 7:11-15
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.
