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?

Say unto them, whosoever he be of all your seed among your generations,.... Whether male or female, in all succeeding ages, as long as the ceremonial law lasted; for females as well as males of the families of the priests ate of the holy things, provided they had no uncleanness on them, but if they had, they might not:

that goeth unto the holy things, which the children of Israel hallow unto the Lord: that approaches to any of the sacrifices which the children of Israel have devoted to the Lord, either to offer them, or even to touch them, and particularly to eat of them; and so Jarchi and Ben Gersom observe, that this going or drawing near is no other than eating; for touching only, a man was not guilty of cutting off:

having his uncleanness upon him; through a leprosy, or running issue, or touching any unclean person or thing, as the following words explain it:

that soul shall be cut off from my presence; excluded from the sanctuary, and the service of it, where the presence of God was; or be removed out of the world by death, either by the civil magistrate, or by the hand of God, by an immediate death, by the pestilence, as the Targum of Jonathan:

I am the Lord; that will avenge the breach of such a law, able to inflict such punishment, and faithful to accomplish every word of his, whether in a way of threatening or promise.

Whosoever he be . . . that goeth unto the holy things--The multitude of minute restrictions to which the priests, from accidental defilement, were subjected, by keeping them constantly on their guard lest they should be unfit for the sacred service, tended to preserve in full exercise the feeling of awe and submission to the authority of God. The ideas of sin and duty were awakened in their breasts by every case to which either an interdict or an injunction was applied. But why enact an express statute for priests disqualified by the leprosy or polluting touch of a carcass [Lev 22:4], when a general law was already in force which excluded from society all persons in that condition? Because priests might be apt, from familiarity, to trifle with religion, and in committing irregularities or sins, to shelter themselves under the cloak of the sacred office. This law, therefore, was passed, specifying the chief forms of temporary defilement which excluded from the sanctuary, that priests might not deem themselves entitled to greater license than the rest of the people; and that so far from being in any degree exempted from the sanctions of the law, they were under greater obligations, by their priestly station, to observe it in its strict letter and its smallest enactments.
