28 and it shall be for Aaron and his sons as their portion forever from the children of Israel; for it is a wave offering: and it shall be a wave offering from the children of Israel of the sacrifices of their peace offerings, even their wave offering to Yahweh.

And it shall be Aaron's. Lest the dignity of the sacred offerings, which are called the holiness of the Lord, should be impaired, strangers are prohibited from partaking of them; for, if it had been permitted that every one should touch them and eat of them, there would have been no distinction between them and ordinary food. Of the priests' portion some parts were common to all their families; but the holy parts were excepted, to the intent that by this particular instance the reverence due to all might be inculcated. The reference to place has the same object, for it was not lawful to eat what was holy within the walls of their houses, in order that it might be distinguished from their common and ordinary food. For the same reason, whatever remained of it was to be burnt, lest, if the flesh became rank, or the bread moldy, their ill savor and filthy appearance might somewhat detract from the dignity of the holy things; for the infirmity of the ancient people had need of childish rudiments, which might still have a tendency to elevate the minds of the pious to things above. This was the object of all these things, that no corruption should creep in which might pollute or render contemptible the service of God.
And it shall be Aaron's and his sons' by a statute for ever from the children of Israel: for it [is] an heave offering: and it shall be an heave offering from the children of Israel of the sacrifice of their (k) peace offerings, [even] their heave offering unto the LORD.
(k) Which were offerings of thanksgiving to God for his benefits.
And it shall be Aaron's and his sons by a statute for ever from the children of Israel,.... That is, the shoulder, which seems particularly meant, though the breast also was theirs, which was at this time given to Moses, he being priest; and this was an everlasting statute and ordinance in all generations, as long as the priesthood of Aaron lasted, until the Messiah should come and put an end to it: and this the children of Israel were always to allow the priests; the shoulder, because Aaron bore their names before the Lord upon his shoulders, for a memorial; and the breast for a like reason, because he bore their names in the breastplate of judgment upon his heart, and their judgment also before the Lord continually, Exodus 28:12,
for it is an heave offering: it is lifted up to the Lord, and therefore is given to his priest:
and it shall be an heave offering from the children of Israel of the sacrifice of their peace offerings, even their heave offering unto the Lord: it being heaved up and given to the priest, it was reckoned an offering to the Lord, and was accepted by him as a peace offering; and it was an emblem of the lifting up of their hearts to God, and of the going up of the affections and desires of their souls to him, and of their serving and worshipping him in spirit and in truth, who is a spirit, and was their Father in heaven, to whom their eyes, hearts, and hands, were to be lifted up.
