11 And this is the law of the sacrifice of peace-offering, which [a man] shall present to Jehovah. 12 If he present it for a thanksgiving, then he shall present with the sacrifice of thanksgiving unleavened cakes mingled with oil, and unleavened wafers anointed with oil, and fine flour saturated with oil, cakes mingled with oil. 13 Besides the cakes, he shall present his offering of leavened bread with the sacrifice of his peace-offering of thanksgiving. 14 And of it he shall present one out of the whole offering as a heave-offering to Jehovah; to the priest that sprinkleth the blood of the peace-offering, to him it shall belong. 15 And the flesh of the sacrifice of his peace-offering of thanksgiving shall be eaten the same day that it is presented; he shall not let any of it remain until the morning. 16 And if the sacrifice of his offering be a vow, or voluntary, it shall be eaten the same day that he presented his sacrifice; on the morrow also the remainder of it shall be eaten; 17 and the remainder 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.
