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 . 16 'But if the sacrifice of his offering is a votive or a freewill offering , it shall be eaten on the day that he offers his sacrifice , and on the next day what is left of it may be eaten ; 17 but what is left over from the flesh of the sacrifice on the third day shall be burned with fire . 18 'So if any of the flesh of the sacrifice of his peace offerings should ever be eaten on the third day , he who offers it will not be accepted , and it will not be reckoned to his benefit. It shall be an offensive thing , and the person who eats of it will bear his own iniquity . 19 'Also the flesh that touches anything unclean shall not be eaten ; it shall be burned with fire . As for other flesh , anyone who is clean may eat such flesh . 20 ' But the person who eats the flesh of the sacrifice of peace offerings which belong to the Lord , in his uncleanness , that person shall be cut off from his people . 21 ' When anyone touches anything unclean , whether human uncleanness , or an unclean animal , or any unclean detestable thing , and eats of the flesh of the sacrifice of peace offerings which belong to the Lord , that person shall be cut off from his people .' "

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.
