11 "These are the instructions regarding the different kinds of peace offerings that may be presented to the Lord . 12 If you present your peace offering as an expression of thanksgiving, the usual animal sacrifice must be accompanied by various kinds of bread made without yeast-thin cakes mixed with olive oil, wafers spread with oil, and cakes made of choice flour mixed with olive oil. 13 This peace offering of thanksgiving must also be accompanied by loaves of bread made with yeast. 14 One of each kind of bread must be presented as a gift to the Lord . It will then belong to the priest who splatters the blood of the peace offering against the altar. 15 The meat of the peace offering of thanksgiving must be eaten on the same day it is offered. None of it may be saved for the next morning. 16 "If you bring an offering to fulfill a vow or as a voluntary offering, the meat must be eaten on the same day the sacrifice is offered, but whatever is left over may be eaten on the second day. 17 Any meat left over until the third day must be completely burned up.

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.
