And not only this, but more is true. For while even among nations of the highest culture and Christian enlightenment many animals are eaten, as, e.g., the oyster, the turtle, the flesh of the horse and the hog, which the law of Moses prohibits; on the other hand, it remains true that, with the sole exception of creatures of the locust tribe, the animals which are allowed for food by the Mosaic code are reckoned suitable for food by almost the entire human family. A notable exception to the fact is indeed furnished in the case of the Hindoos, and also the Buddhists (who follow an Indian religion), who, as a rule, reject all animal food, and especially, in the case of the former, the flesh of the cow, as not to be eaten. But this exception is quite explicable by considerations into which we cannot here enter at length, but which do not affect the significance of the general fact.
And, again, on the other hand, it may also be said that, as a general rule, the appetite of the great majority of enlightened and cultivated nations revolts against using as food the greater part of the animals which this code prohibits. Birds of prey, for instance, and the carnivora generally, animals having paws, and reptiles, for the most part, by a kind of universal instinct among cultivated peoples, are judged unfit for human food.
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.
But when we now seek to ascertain upon what principle certain animals were permitted and others forbidden as food, it must be confessed that we have before us a very difficult question, and one to which, accordingly, very diverse answers have been given. In general, indeed, we are expressly told that the object of this legislation, as of all else in this book of laws, was moral and spiritual. Thus, we are told in so many words (vv. 43-45) that Israel was to abstain from eating or touching the unclean, on the ground that they were to be holy, because the Lord their God was holy. But to most this only increases the difficulty. What possible connection could there be between eating, or abstinence from eating, animals which do not chew the cud, or fishes which have not scales, and holiness of life?
In answer to this question, some have supposed a mystical connection between the soul and the body, such that the former is defiled by the food which is received and assimilated by the latter. In support of this theory, appeal has been made to ver. 44 of this chapter, which, in the Septuagint translation, is rendered literally: "Ye shall not defile your souls." But, as often in Hebrew, the original expression here is simply equivalent to our compound pronoun "yourselves," and is therefore so translated both in the Authorised and the Revised Versions. As for any other proof of such a mystical evil influence of the various kinds of food prohibited in this chapter, there is simply none at all.
Others, again, have sought the explication of these facts in the undoubted Divine purpose of keeping Israel separate from other nations; to secure which separation this special dietetic code, with other laws regarding the clean and the unclean, was given them. That these laws have practically helped to keep the children of Israel separate from other nations, will not be denied; and we may therefore readily admit, that inasmuch as the food of the Hebrews has differed from that of the nations among whom they have dwelt, this separation of the nation may therefore have been included in the purpose of God in these regulations. However, it is to be observed that in the law itself the separation of Israel from other nations is represented, not as the end to be attained by the observance of these food laws, but instead, as a fact already existing, which is given as a reason why they should keep these laws (xx. 24, 25). Moreover, it will be found impossible, by reference to this principle alone, to account for the details of the laws before us. For the question is not merely why there should have been food laws, but also why these laws should have been such as they are? The latter question is not adequately explained by reference to God's purpose of keeping Israel separate from the nations.
Some, again, have held that the explanation of these laws was to be found simply in the design of God, by these restrictions, to give Israel a profitable moral discipline in self-restraint and control of the bodily appetites; or to impose, in this way, certain conditions and limitations upon their approach to Him, which should have the effect of deepening in them the sense of awe and reverence for the Divine majesty of God, as their King. Of this theory it may be said, as of the last-named, that there can be no doubt that in fact these laws did tend to secure these ends; but that yet, on the other hand, the explanation is still inadequate, inasmuch as it only would show why restrictions of some kind should have been ordered, and not, in the least, why the restrictions should have been such, in detail, as we have here.
Quite different from any of these attempted explanations is that of many who have sought to explain the law allegorically. We are told by such that Israel was forbidden the flesh of certain animals, because they were regarded as typifying by their character certain sins and vices, as, on the other hand, those which were permitted as food were regarded as typifying certain moral virtues. Hence, it is supposed by such that the law tended to the holiness of Israel, in that it was, so to speak, a continual object-lesson, a perpetually acted allegory, which should continually remind them of the duty of abstaining from the typified sins and of practising the typified virtues. But, assuredly, this theory cannot be carried out. Animals are in this law prohibited as food whose symbolic meaning elsewhere in Scripture is not always bad, but sometimes good. The lion, for example, as having paws, is prohibited as food; and yet it is the symbol of our blessed Lord, "the Lion of the tribe of Judah." Nor is there the slightest evidence that the Hebrews ever attached any such allegorical significance to the various prescriptions of this chapter as the theory would require.
Other expositors allegorise in a different but no more satisfactory manner. Thus a popular, and, it must be added, most spiritual and devout expositor, sets forth the spiritual meaning of the required conjunction of the two marks in clean animals of the chewing of the cud and the dividing of the hoof in this wise: "The two things were inseparable in the case of every clean animal. And, as to the spiritual application, it is of the very last importance in a practical point of view.... A man may profess to love and feed upon, to study and ruminate over, the Word of God—the pasture of the soul; but if his footprints along the pathway of life are not such as the Word requires, he is not clean."
