The bearing of these facts upon our exposition is plain. They certainly suggest, at least, that this law of Lev. xi. may, after all, very possibly have a deep foundation both in the nature of man and that of the things permitted or forbidden; and they also raise the question as to how far exceptions and divergencies from this law, among peoples of culture, may possibly be due to a diversity in external physical and climatic conditions, because of which that which may be wholesome and suitable food in one place--the wilderness of Sinai, or Palestine, for instance--may not be wholesome and suitable in other lands, under different physical conditions. We do not yet enter into this question, but barely call attention to it, as adapted to check the hasty judgment of many, that such a law as this is necessarily puerile and unworthy of God. But while it is of no small consequence to note this agreement in the fundamental ideas of this law with widely extended instincts and habits of mankind, on the other hand, it is also of importance to emphasise the contrast which it exhibits with similar codes of law among other peoples. For while, as has just been remarked, there are many most suggestive points of agreement between the Mosaic distinctions of clean and unclean and those of other nations, on the other hand, remarkable contrasts appear, even in the case of those people with whom, like the Egyptians, the Hebrews had been most intimately associated. In the Egyptian system of dietary law, for instance, the distinction of clean and unclean in food was made to apply, not only in the animal, but also in the vegetable world; and, again, while all fishes having fins and scales are permitted as food in the Mosaic law, no fishes whatever are permitted by the Egyptian code. But more significant than such difference in details is the difference in the religious conception upon which such distinctions are based. In Egypt, for example, animals were reckoned clean or unclean according as they were supposed to have more predominant the character of the good Osiris or of the evil Typhon. Among the ancient Persians, those were reckoned clean which were supposed to be the creation of Ormazd, the good Spirit, and those unclean whose origin was attributed to Ahriman, the evil Spirit. In India, the prohibition of flesh as food rests on pantheistic assumptions. Not to multiply examples, it is easy to see that, without anticipating anything here with regard to the principle which determined the Hebrew distinctions, it is certain that of such dualistic or pantheistic principles as are manifested in these and other instances which might be named, there is not a trace in the Mosaic law. How significant and profoundly instructive is the contrast here, will only fully appear when we see what in fact appears to have been the determining principle in the Mosaic legislation.
