11 'Now this is the law of the sacrifice of peace offerings which shall be presented to the Lord . 12 'If he offers it by way of thanksgiving , then along with the sacrifice of thanksgiving he shall offer unleavened cakes mixed with oil , and unleavened wafers spread with oil , and cakes of well stirred fine flour mixed with oil . 13 'With the sacrifice of his peace offerings for thanksgiving , he shall present his offering with cakes of leavened bread . 14 'Of this he shall present one of every offering as a contribution to the Lord ; it shall belong to the priest who sprinkles the blood of the peace offerings . 15 ' Now as for the flesh of the sacrifice of his thanksgiving peace offerings , it shall be eaten on the day of his offering ; he shall not leave any of it over until 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.
