Leviticus 11:3

Laws Relating to Clean and Unclean Animals - Leviticus 11 The regulation of the sacrifices and institution of the priesthood, by which Jehovah opened up to His people the way of access to His grace and the way to sanctification of life in fellowship with Him, were followed by instructions concerning the various things which hindered and disturbed this living fellowship with God the Holy One, as being manifestations and results of sin, and by certain rules for avoiding and removing these obstructions. For example, although sin has its origin and proper seat in the soul, it pervades the whole body as the organ of the soul, and shatters the life of the body, even to its complete dissolution in death and decomposition; whilst its effects have spread from man to the whole of the earthly creation, inasmuch as not only did man draw nature with him into the service of sin, in consequence of the dominion over it which was given him by God, but God Himself, according to a holy law of His wise and equitable government, made the irrational creature subject to "vanity" and "corruption" on account of the sin of man (Rom 8:20-21), so that not only did the field bring forth thorns and thistles, and the earth produce injurious and poisonous plants (see at Gen 3:18), but the animal kingdom in many of its forms and creatures bears the image of sin and death, and is constantly reminding man of the evil fruit of his fall from God. It is in this penetration of sin into the material creation that we may find the explanation of the fact, that from the very earliest times men have neither used every kind of herb nor every kind of animal as food; but that, whilst they have, as it were, instinctively avoided certain plants as injurious to health or destructive to life, they have also had a horror…

The ceremonial law is described by the apostle (Heb 9:9, Heb 9:10) to consist, not only "in gifts and sacrifices," which hitherto have been treated of in this book, but "in meats, and drinks, and divers washings" from ceremonial uncleanness, the laws concerning which begin with this chapter, which puts a difference between some sorts of flesh-meat and others, allowing some to be eaten as clean and forbidding others as unclean. "There is one kind of flesh of men." Nature startles at the thought of eating this, and none do it but such as have arrived at the highest degree of barbarity, and become but one remove from brutes; therefore there needed no law against it. But there is "another kind of flesh of beasts," concerning which the law directs here (Lev 11:1-8), "another of fishes" (Lev 11:9-12), "another of birds" (Lev 11:13-19), and "another of creeping things," which are distinguished into two sorts, flying creeping things (Lev 11:20-28) and creeping things upon the earth (Lev 11:29-43). And the law concludes with the general rule of holiness, and reasons for it (Lev 11:44, etc.).
