Here is the law, 1. Concerning flying insects, as flies, wasps, bees, etc.; these they might not eat (Lev 11:20), nor indeed are they fit to be eaten; but there were several sorts of locusts which in those countries were very good meat, and much used: John Baptist lived upon them in the desert, and they are here allowed them, Lev 11:21, Lev 11:22. 2. Concerning the creeping things on the earth; these were all forbidden (Lev 11:29, Lev 11:30, and again, Lev 11:41, Lev 11:42); for it was the curse of the serpent that upon his belly he should go, and therefore between him and man there was an enmity put (Gen 3:15), which was preserved by this law. Dust is the meat of the creeping things, and therefore they are not fit to be man's meat. 3. Concerning the dead carcasses of all these unclean animals. (1.) Every one that touched them was to be unclean until the evening, Lev 11:24-28. This law is often repeated, to possess them with a dread of every thing that was prohibited, though no particular reason for the prohibition did appear, but only the will of the Law-maker. Not that they were to be looked upon as defiling to the conscience, or that it was a sin against God to touch them, unless done in contempt of the law: in many cases, somebody must of necessity touch them, to remove them; but it was a ceremonial uncleanness they contracted, which for the time forbade them to come into the tabernacle, or to eat of any of the holy things, or so much as to converse familiarly with their neighbours. But the uncleanness continued only till the evening, to signify that all ceremonial pollutions were to come to an end by the death of Christ in the evening of the world. And we must learn, by daily renewing our repentance every night for the sins of the day, to cleanse ourselves from the pollution we contract by them, that we may not lie down in our uncleanness. Even unclean animals they might touch while they were alive without contracting any ceremonial uncleanness by it, as horses and dogs, because they were allowed to use them for service; but they might not touch them when they were dead, because they might not eat their flesh; and what must not be eaten must not be touched, Gen 3:3. (2.) Even the vessels, or other things they fell upon, were thereby made unclean until the evening (Lev 11:32), and if they were earthen vessels they must be broken, Lev 11:33. This taught them carefully to avoid every thing that was polluting, even in their common actions. Not only the vessels of the sanctuary, but every pot in Jerusalem and Judah, must be holiness to the Lord, Zac 14:20, Zac 14:21. The laws in these cases are very critical, and the observance of them would be difficult, we should think, if every thing that a dead mouse or rat, for instance, falls upon must be unclean; and if it were an oven, or ranges for pots, they must all be broken down, Lev 11:35. The exceptions also are very nice, Lev 11:36, etc. All this was designed to exercise them to a constant care and exactness in their obedience, and to teach us, who by Christ are delivered from these burdensome observances, not to be less circumspect in the more weighty matters of the law. We ought as industriously to preserve our precious souls from the pollutions of sin, and as speedily to cleanse them when they are polluted, as they were to preserve and cleanse their bodies and household goods from those ceremonial pollutions.

Any sowing seed - If any part of an impure carcass fall accidentally on seed about to be sown, it shall not on that account be deemed unclean; but if the water put to the seed to prepare it for being sown, shall be touched by such impure carcass, the seed shall be considered as unclean, Lev 11:38. Probably this may be the meaning of these passages.

But if any water be put upon the seed,.... Either accidentally or on purpose; whether on sowing seed, and with water with which they water the field, as Aben Ezra interprets it; or on seed used for food, by steeping it in water, as sometimes wheat is, and boiled; and whether it is water or the rest of the liquors, and whether they are put on the seed, or the seed falls into them, it matters not, as Jarchi says:

and any part of their carcass fall thereon; that is, on the seed, though Aben Ezra observes, some say upon the water: the Targum of Jonathan adds, in its moisture, or while it is wet; and so may be thought to be more susceptible of impurity from the touch of a dead reptile, or any part of it, and which would render it unfit for sowing or eating, until it was dried and cleansed; yea, Jarchi says, if it falls thereon, even after it is dried:

it shall be unclean unto you; unfit for use.

whosoever doth touch them, when . . . dead, shall be unclean until the even--These regulations must have often caused annoyance by suddenly requiring the exclusion of people from society, as well as the ordinances of religion. Nevertheless they were extremely useful and salutary, especially as enforcing attention to cleanliness. This is a matter of essential importance in the East, where venomous reptiles often creep into houses and are found lurking in boxes, vessels, or holes in the wall; and the carcass of one of them, or a dead mouse, mole, lizard, or other unclean animal, might be inadvertently touched by the hand, or fall on clothes, skin bottles, or any article of common domestic use. By connecting, therefore, the touch of such creatures with ceremonial defilement, which required immediately to be removed, an effectual means was taken to prevent the bad effects of venom and all unclean or noxious matter.
