Leviticus 2:3
3. the remnant of the meat offering shall be Aaron's and his sons'—The circumstance of a portion of it being appropriated to the use of the priests distinguishes this from a burnt offering. They alone were to partake of it within the sacred precincts, as among "the most holy things."
Leviticus 7:31
29-34. He that offereth the sacrifice of his peace offerings unto the Lord—In order to show that the sacrifice was voluntary, the offerer was required to bring it with his own hands to the priest. The breast having been waved to and fro in a solemn manner as devoted to God, was given to the priests; it was assigned to the use of their order generally, but the right shoulder was the perquisite of the officiating priest.
Proverbs 7:14
13-15. The preparations for a feast do not necessarily imply peculiar religious professions. The offerer retained part of the victim for a feast (Le 3:9, &c.). This feast she professes was prepared for him whom she boldly addresses as one sought specially to partake of it.
