Leviticus 2:3

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, 1 Corinthians 9:13 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 holy; or, as it is in the original, "holiness of holiness", the most holy of all.
