verses 24-26
In Lev 11:24-28 there follow still further and more precise instructions, concerning defilement through contact with the carcases (i.e., the carrion) of the animals already mentioned. These instructions relate first of all (Lev 11:24 and Lev 11:25) to aquatic and winged animals, which were not to be eaten because they were unclean (the expression “for these” in Lev 11:24 relates to them); and then (Lev 11:26-28) to quadrupeds, both cattle that have not the hoof thoroughly divided and do not ruminate (Lev 11:26), and animals that go upon their hands, i.e., upon paws, and have no hoofs, such as cats, dogs, bears, etc.
verses 27-28
The same rule was applicable to all these animals: “whoever toucheth the carcase of them shall be unclean until the even,” i.e., for the rest of the day; he was then of course to wash himself. Whoever carried their carrion, viz., to take it away, was also unclean till the evening, and being still more deeply affected by the defilement, he was to wash his clothes as well.
verses 29-38
To these there are attached analogous instructions concerning defilement through contact with the smaller creeping animals (Sherez), which formed the fourth class of the animal kingdom; though the prohibition against eating these animals is not introduced till Lev 11:41, Lev 11:42, as none of these were usually eaten. Sherez, the swarm, refers to animals which swarm together in great numbers (see at Gen 1:21), and is synonymous with remes (cf. Gen 7:14 and Gen 7:21), “the creeping;” it denotes the smaller land animals which move without feet, or with feet that are hardly perceptible (see at Gen 1:24). Eight of the creeping animals are named, as defiling not only the men with whom they might come in contact, but any domestic utensils and food upon which they might fall; they were generally found in houses, therefore, or in the abodes of men. חלד is not the mole (according to Saad. Ar. Abys., etc.), although the Arabs still call this chuld, but the weasel (lxx, Onk., etc.), which is common in Syria and Palestine, and is frequently mentioned by the Talmudists in the feminine form חוּלדה, as an animal which caught birds (Mishn. Cholin iii. 4), which would run over the wave-loaves with a sherez in its mouth (Mishn. Tohor. iv. 2), and which could drink water out of a vessel (Mishn. Para ix. 3). עכבּר is the mouse (according to the ancient versions and the Talmud), and in 1Sa 6:5 the field-mouse, the scourge of the fields, not the jerboa, as Knobel
