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.

King James Version

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.

English Standard Version

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.

The Message

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.

New King James Version

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.

New Living Translation

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.

Matthew Henry's Commentary on Leviticus 7:15-18

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.
