And if ye offer a sacrifice of peace offerings unto the LORD, ye shall offer it at your own will.
If ye offer a sacrifice of peace offerings. Those which included thank offerings, or offerings made for vows, were always free-will offerings. Except the portions which, being waved and heaved, became the property of the priests (see Leviticus 3:1-17), the rest of the victim was eaten by the offerer and his friends, under the following regulations, however-that, if thank offerings, they were to be eaten on the day of their presentation; and if a free-will offering, although it might be eaten on the second day, yet if any remains of it were left until the third day, it was to be burnt, or deep criminality was incurred by the person who then ventured to partake of it. The reason of this strict prohibition seems to have been to prevent any intrinsic holiness or mysterious virtue being superstitiously attached to meat offered on the altar.
Verse 8. That soul shall be cutoff from among his people. This phrase means excommunication, or perhaps death, (cf. Exodus 28:43; Numbers 14:34; Numbers 18:22; Numbers 18:32, etc.)
