But the rest of the grain offering shall be for Aaron and his sons; it is a most holy part of the LORD’s food offerings.
There were some meat-offerings that were only appendices to the burnt-offerings, as that which was offered with the daily sacrifice (Exo 29:38, Exo 29:39) and with the peace-offerings; these had drink-offerings joined with them (see Num 15:4, Num 15:7, Num 15:9, Num 15:10), and in these the quantity was appointed.
Commenting on Leviticus 2:1-10
And the remnant of the meat offering shall be Aaron's and his sons',.... Which not only shows the care taken by the Lord for the maintenance of the priests, from whence the apostle argues for the support of ministers of the Gospel, Co1 9:13 but denotes that such who are made priests unto God by Christ, have a right to feed upon Christ the meat...
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."
