Those that had a natural blemish, though they were forbidden to do the priests' work, were yet allowed to eat of the holy things: and the Jewish writers say that "to keep them from idleness they were employed in the wood-room, to pick out that which was worm-eaten, that it might not be used in the fire upon the altar; they might also be employed in the judgment of leprosy:" but,

I.Those that were under any ceremonial uncleanness, which possibly they contracted by their own fault, might no so much as eat of the holy things while they continued in their pollution. 1. Some pollutions were permanent, as a leprosy or a running issue, Lev 22:4. These separated the people from the sanctuary, and God would show that they were so far from being more excusable that really they were more abominable in a priest. 2. Others were more transient, as the touching of a dead body, or any thing else that was unclean, from which, after a certain time, a man was cleansed by bathing his flesh in water, Lev 22:6. But whoever was thus defiled might not eat of the holy things, under pain of God's highest displeasure, who said, and ratified the saying, That soul shall be cut off from my presence, Lev 22:3. Our being in the presence of God, and attending upon him, will be so far from securing us that it will but the more expose us to God's wrath, if we dare to draw nigh to him in our uncleanness. The destruction shall come from the presence of the Lord (Th2 1:9), as the fire by which Nadab and Abihu died came from before the Lord. Thus those who profane the holy word of God will be cut off by that word which they make so light of; it shall condemn them. They are again warned of their danger if they eat the holy thing in their uncleanness (Lev 22:9), lest they bear sin, and die therefore. Note, (1.) Those contract great guilt who profane sacred things, by touching them with unhallowed hands. Eating the holy things signified an interest in the atonement; but, if they ate of them in their uncleanness, they were so far from lessening their guilt that they increased it: They shall bear sin. (2.) Sin is a burden which, if infinite mercy prevent not, will certainly sink those that bear it: They shall die therefore. Even priests may be ruined by their pollutions and presumptions.

II.As to the design of this law we may observe, 1. This obliged the priests carefully to preserve their purity, and to dread every thing that would defile them. The holy things were their livelihood; if they might not eat of them, how must they subsist? The more we have to lose of comfort and honour by our defilement, the more careful we should be to preserve our purity. 2. This impressed the people with a reverence for the holy things, when they saw the priests themselves separated from them (as the expression is, Lev 22:2) so long as they were in their uncleanness. He is doubtless a God of infinite purity who kept his immediate attendants under so strict a discipline. 3. This teaches us carefully to watch against all moral pollutions, because by them we are unfitted to receive the comfort of God's sanctuary. Though we labour not under habitual deformities, yet actual defilements deprive us of the pleasure of communion with God; and therefore he that is washed needeth to wash his feet (Joh 13:10), to wash his hands, and so to compass the altar, Psa 26:6. Herein we have need to be jealous over ourselves, lest (as it is observably expressed here) we profane God's holy name in those things which we hallow unto him, Lev 22:2. If we affront God in those very performances wherein we pretend to honour him, and provoke him instead of pleasing him, we shall make up but a bad account shortly; yet thus we do if we profane God's name, by doing that in our uncleanness which pretends to be hallowed to him.

Speak unto Aaron and to his sons, that they separate themselves - The same subject is continued in this chapter as in the preceding, with this addition, that besides the perfection of the priests, it was indispensably necessary that the sacrifices also should be perfect. In the service of God, according to the law, neither an imperfect offering nor an imperfect offerer could be admitted. What need then of a mediator between a holy God and sinful men! And can we expect that any of our services, however sincere and well-intentioned, can be accepted, unless offered on that living Altar that sanctifies the gift?

Speak unto Aaron and to his sons,.... The priests; the children of Israel or the common people are not mentioned, as having no concern in the following laws about eating holy things:

that they separate themselves from the holy things of the children of Israel; both from offering their lawful sacrifices, which was the business of their office when pure, and chiefly from eating that part of them which was their due, and was allowed them; neither of these they were to do, particularly the latter, when they were in any uncleanness, as the following words show:

and that, they profane not my holy name in those things which they hallow unto me; which the children of Israel set apart and devoted to his service; which they would do, by eating their part of them when unclean, and thereby show little reverence to that holy name to which they were devoted; or which the priests themselves sanctified, by offering them to him; for Jarchi says, this takes in the holiness of the priests themselves; but the former seems best, and is confirmed in Lev 22:3,

I am the Lord; who is holy himself, and whose holy things these are, and will be sanctified by those that draw nigh unto him.
