Leviticus 2:3

“And the remnant of the meat offering shall be Aaron’s and his sons’, etc.] 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, (<460913>1 Corinthians 9:13,14) but denotes that such who are made priests unto God by Christ, have a right to feed upon Christ the meat offering by faith; who is that altar and meat offering, which none but such have a right to eat of: it is a thing most holy of the offerings of the Lord made by fire; some offerings with the Jews were only holy things, or, as they call them, “light” holy things, comparatively speaking; others were heavy holy things, or most…”

“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."”

“A thing most holy - literally, a holy of holies. All offerings were holy, including the portions of the peace-offerings which were eaten by the laity; but that was “most holy” of which every part was devoted either to the altar, or to the use of the priests. Such were the minchaahs, the showbread, the incense, and the flesh of the sin-offerings and trespass-offerings. Compare the similar distinction between places Exodus 26:33. The most holy food was eaten in “the holy place,” that is the precinct of the tabernacle, probably in the priests’ lodgings; but the priests’ portion of the peace-offerings might be eaten by the priests and their families in any “clean place” Leviticus 10:12-14.…”

“Sons - To be eaten by them, Lev 6:16. Most holy - Or such as were to be eaten only by the priests, and that only in the holy place near the altar. Leviticus 2:4”

“2:3 rest of the grain offering: A portion of the fire offerings was generally reserved for the priest as food (see 6:16-17). Exceptions included the whole burnt offering (the priest received only the hide; see 7:8), offerings given by the priest for himself (4:3-12; 6:19-23), or offerings made for the entire community (4:13-21). In these cases, the offering was to be entirely burned. The grain offering provided the priests with bread for their diet. • most holy (Hebrew qodesh qodashim, “holy of holies”): Both God and what belongs to him are holy. “Most holy” designates the priestly share as taken from the holy offering and reserved for a special function. This description is used for the…”
