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.

The ferret - אנקה anakah, from אנק anak, to groan, to cry out: a species of lizard, which derives its name from its piercing, doleful cry. See Bochart, vol. ii., col. 1066.

The chameleon - כח coach. Bochart contends that this is the waril or guaril, another species of lizard, which derives its name from its remarkable strength and vigor in destroying serpents, the Hebrew כח cach signifying to be strong, firm, vigorous: it is probably the same with the mongoose, a creature still well known in India, where it is often domesticated in order to keep the houses free from snakes, rats, mice, etc.

The lizard - לטאה letaah. Bochart contends that this also is a species of lizard, called by the Arabs wahara, which creeps close to the ground, and is poisonous.

The snail - חמט chomet, another species of lizard, according to Bochart, called huluka by the Arabians, which lives chiefly in the sand - Vol. ii., col. 1075.

The mole - תנשמת tinshameth, from נשם nasham, to breathe. Bochart seems to have proved that this is the chameleon, which has its Hebrew name from its wide gaping mouth, very large lungs, and its deriving its nourishment from small animals which float in the air, so that it has been conjectured by some to feed on the air itself - Vol. iii., col. 1073. A bird of the same name is mentioned Lev 11:18, which Bochart supposes to be the night-owl - Vol. iii., col. 286.

These are unclean to you of all that creep,.... Unfit for food, and not to be touched, at least when dead, as in the next clause, that is, these eight sorts of creeping things before mentioned, as the Targum of Jonathan expresses it, and these only, as Maimonides says (r):

whosoever doth touch them when they are dead shall be unclean until the even; for touching them while alive did not defile, only when dead; and this the Jews interpret, while they are in the case in which they died, that is, while they are moist; for, as Ben Gersom says, if they are so dry, as that they cannot return to their moisture, they do not defile; for which reason, neither the bones, nor nails, nor nerves, nor skin of these creeping things, defile; but, they say (s), while the back bone is whole, and the bones cleave to it, then a creeping thing is reckoned moist, and while it is so it defiles. (r) Hilchot, Abot Hatumaot, c. 4. sect. 14. (s) Maimon. & Bartenora in Misn. Niddah, c. 7. sect. 1.

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.
