15 The meat of their fellowship offering of thanksgiving must be eaten on the day it is offered; they must leave none of it till morning. 16 " 'If, however, their offering is the result of a vow or is a freewill offering, the sacrifice shall be eaten on the day they offer it, but anything left over may be eaten on the next day. 17 Any meat of the sacrifice left over till the third day must be burned up. 18 If any meat of the fellowship offering is eaten on the third day, the one who offered it will not be accepted. It will not be reckoned to their credit, for it has become impure; the person who eats any of it will be held responsible. 19 " 'Meat that touches anything ceremonially unclean must not be eaten; it must be burned up. As for other meat, anyone ceremonially clean may eat it. 20 But if anyone who is unclean eats any meat of the fellowship offering belonging to the Lord, they must be cut off from their people. 21 Anyone who touches something unclean-whether human uncleanness or an unclean animal or any unclean creature that moves along the ground[1] -and then eats any of the meat of the fellowship offering belonging to the Lord must be cut off from their people.' "
15 And the flesh of the sacrifice of his peace offerings for thanksgiving shall be eaten the same day that it is offered; he shall not leave any of it until the morning. 16 But if the sacrifice of his offering be a vow, or a voluntary offering, it shall be eaten the same day that he offereth his sacrifice: and on the morrow also the remainder of it shall be eaten: 17 But the remainder of the flesh of the sacrifice on the third day shall be burnt with fire. 18 And if any of the flesh of the sacrifice of his peace offerings be eaten at all on the third day, it shall not be accepted, neither shall it be imputed unto him that offereth it: it shall be an abomination, and the soul that eateth of it shall bear his iniquity. 19 And the flesh that toucheth any unclean thing shall not be eaten; it shall be burnt with fire: and as for the flesh, all that be clean shall eat thereof. 20 But the soul that eateth of the flesh of the sacrifice of peace offerings, that pertain unto the Lord, having his uncleanness upon him, even that soul shall be cut off from his people. 21 Moreover the soul that shall touch any unclean thing, as the uncleanness of man, or any unclean beast, or any abominable unclean thing, and eat of the flesh of the sacrifice of peace offerings, which pertain unto the Lord, even that soul shall be cut off from his people.
15 And the flesh of the sacrifice of his peace offerings for thanksgiving shall be eaten on the day of his offering. He shall not leave any of it until the morning. 16 But if the sacrifice of his offering is a vow offering or a freewill offering, it shall be eaten on the day that he offers his sacrifice, and on the next day what remains of it shall be eaten. 17 But what remains of the flesh of the sacrifice on the third day shall be burned up with fire. 18 If any of the flesh of the sacrifice of his peace offering is eaten on the third day, he who offers it shall not be accepted, neither shall it be credited to him. It is tainted, and he who eats of it shall bear his iniquity. 19 "Flesh that touches any unclean thing shall not be eaten. It shall be burned up with fire. All who are clean may eat flesh, 20 but the person who eats of the flesh of the sacrifice of the Lord's peace offerings while an uncleanness is on him, that person shall be cut off from his people. 21 And if anyone touches an unclean thing, whether human uncleanness or an unclean beast or any unclean detestable creature, and then eats some flesh from the sacrifice of the Lord's peace offerings, that person shall be cut off from his people."
15 Eat the meat from the Peace-Offering of thanksgiving the same day it is offered. Don't leave any of it overnight. 16 "If the offering is a Votive-Offering or a Freewill-Offering, it may be eaten the same day it is sacrificed and whatever is left over on the next day may also be eaten. 17 But any meat from the sacrifice that is left to the third day must be burned up. 18 If any of the meat from the Peace-Offering is eaten on the third day, the person who has brought it will not be accepted. It won't benefit him a bit - it has become defiled meat. And whoever eats it must take responsibility for his iniquity. 19 Don't eat meat that has touched anything ritually unclean; burn it up. Any other meat can be eaten by those who are ritually clean. 20 But if you're not ritually clean and eat meat from the Peace-Offering for God, you will be excluded from the congregation. 21 And if you touch anything ritually unclean, whether human or animal uncleanness or an obscene object, and go ahead and eat from a Peace-Offering for God, you'll be excluded from the congregation."
15 'The flesh of the sacrifice of his peace offering for thanksgiving shall be eaten the same day it is offered. He shall not leave any of it until morning. 16 But if the sacrifice of his offering is a vow or a voluntary offering, it shall be eaten the same day that he offers his sacrifice; but on the next day the remainder of it also may be eaten; 17 the remainder of the flesh of the sacrifice on the third day must be burned with fire. 18 And if any of the flesh of the sacrifice of his peace offering is eaten at all on the third day, it shall not be accepted, nor shall it be imputed to him; it shall be an abomination to him who offers it, and the person who eats of it shall bear guilt. 19 'The flesh that touches any unclean thing shall not be eaten. It shall be burned with fire. And as for the clean flesh, all who are clean may eat of it. 20 But the person who eats the flesh of the sacrifice of the peace offering that belongs to the Lord, while he is unclean, that person shall be cut off from his people. 21 Moreover the person who touches any unclean thing, such as human uncleanness, an unclean animal, or any abominable unclean thing, and who eats the flesh of the sacrifice of the peace offering that belongs to the Lord, that person shall be cut off from his people.' "
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. 18 If any of the meat from the peace offering is eaten on the third day, the person who presented it will not be accepted by the Lord . You will receive no credit for offering it. By then the meat will be contaminated; if you eat it, you will be punished for your sin. 19 "Meat that touches anything ceremonially unclean may not be eaten; it must be completely burned up. The rest of the meat may be eaten, but only by people who are ceremonially clean. 20 If you are ceremonially unclean and you eat meat from a peace offering that was presented to the Lord, you will be cut off from the community. 21 If you touch anything that is unclean (whether it is human defilement or an unclean animal or any other unclean, detestable thing) and then eat meat from a peace offering presented to the Lord, you will be cut off from the community."
Matthew Henry's Commentary on Leviticus 7:15-21
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.
