Now that Aaron was consecrated a high priest over the house of God, God spoke to him with Moses, and appointed them both as joint-commissioners to deliver his will to the people. He spoke both to Moses and to Aaron about this matter; for it was particularly required of the priests that they should put a difference between clean and unclean, and teach the people to do so. After the flood, when God entered into covenant with Noah and his sons, he allowed them to eat flesh (Gen 9:13), whereas before they were confined to the productions of the earth. But the liberty allowed to the sons of Noah is here limited to the sons of Israel. They might eat flesh, but not all kinds of flesh; some they must look upon as unclean and forbidden to them, others as clean and allowed them. The law in this matter is both very particular and very strict. But what reason can be given for this law? Why may not God's people have as free a use of all the creatures as other people? 1. It is reason enough that God would have it so: his will, as it is law sufficient, so it is reason sufficient; for his will is his wisdom. He saw good thus to try and exercise the obedience of his people, not only in the solemnities of his altar, but in matters of daily occurrence at their own table, that they might remember they were under authority. Thus God had tried the obedience of man in innocency, by forbidding him to eat of one particular tree. 2. Most of the meats forbidden as unclean are such as were really unwholesome, and not fit to be eaten; and those of them that we think wholesome enough, and use accordingly, as the rabbit, the hare, and the swine, perhaps in those countries, and to their bodies, might be hurtful. And then God in this law did by them but as a wise and loving father does by his children, whom he restrains from eating that which he knows will make them sick. Note, The Lord is for the body, and it is not only folly, but sin against God, to prejudice our health for the pleasing of our appetite. 3. God would thus teach his people to distinguish themselves from other people, not only in their religious worship, but in the common actions of life. Thus he would show them that they must not be numbered among the nations. It should seem there had been, before this, some difference between the Hebrews and other nations in their food, kept up by tradition; for the Egyptians and they would not eat together, Gen 43:32. And even before the flood there was a distinction of beasts into clean and not clean (Gen 7:2), which distinction was quite lost, with many other instances of religion, among the Gentiles. But by this law it is reduced to a certainty, and ordered to be kept up among the Jews, that thus, by having a diet peculiar to themselves, they might be kept from familiar conversation with their idolatrous neighbours, and might typify God's spiritual Israel, who not in these little things, but in the temper of their spirits, and the course of their lives, should be governed by a sober singularity, and not be conformed to this world. The learned observe further, That most of the creatures which by this law were to be abominated as unclean were such as were had in high veneration among the heathen, not so much for food as for divination and sacrifice to their gods; and therefore those are here mentioned as unclean, and an abomination, which yet they would not be in any temptation to eat, that they might keep up a religious loathing of that for which the Gentiles had a superstitious value. The swine, with the later Gentiles, was sacred to Venus, the owl to Minerva, the eagle to Jupiter, the dog to Hecate, etc., and all these are here made unclean. As to the beasts, there is a general rule laid down, that those which both part the hoof and chew the cud were clean, and those only: these are particularly mentioned in the repetition of this law (Deu 14:4, Deu 14:5), where it appears that the Israelites had variety enough allowed them, and needed not to complain of the confinement they were under. Those beasts that did not both chew the cud and divide the hoof were unclean, by which rule the flesh of swine, and of hares, and of rabbits, was prohibited to them, though commonly used among us. Therefore, particularly at the eating of any of these, we should give thanks for the liberty granted us in this matter by the gospel, which teaches us that every creature of God is good, and we are to call nothing common or unclean. Some observe a significancy in the rule here laid down for them to distinguish by, or at least think it may be alluded to. Meditation, and other acts of devotion done by the hidden man of the heart, may be signified by the chewing of the cud, digesting our spiritual food; justice and charity towards men, and the acts of a good conversation, may be signified by the dividing of the hoof. Now either of these without the other will not serve to recommend us to God, but both must go together, good affections in the heart and good works in the life: if either be wanting, we are not clean, surely we are not clean. Of all the creatures here forbidden as unclean, none has been more dreaded and detested by the pious Jews than swine's flesh. Many were put to death by Antiochus because they would not eat it. This, probably, they were most in danger of being tempted to, and therefore possessed themselves and their children with a particular antipathy to it, calling it not by its proper name, but a strange thing. It should seem the Gentiles used it superstitiously (Isa 65:4), they eat swine's flesh; and therefore God forbids all use of it to his people, lest they should learn of their neighbours to make that ill use of it. Some suggest that the prohibition of these beasts as unclean was intended to be a caution to the people against the bad qualities of these creatures. We must not be filthy nor wallow in the mire as swine, nor be timorous and faint-hearted as hares, nor dwell in the earth as rabbits; let not man that is in honour make himself like these beasts that perish. The law forbade, not only the eating of them, but the very touching of them; for those that would be kept from any sin must be careful to avoid all temptations to it, and every thing that looks towards it or leads to it.

And the Lord spake unto Moses - In the preceding chapter the priests are expressly forbidden to drink wine; and the reason for this law is given also, that they might be able at all times to distinguish between clean and unclean, and be qualified to teach the children of Israel all the statutes which the Lord had spoken, Lev 10:10, Lev 10:11; for as inebriation unfits a person for the regular performance of every function of life, it must be especially sinful in those who minister in holy things, and to whom the teaching of the ignorant, and the cure of souls in general, are entrusted. Scheuchzer has remarked that no Christian state has made any civil law against drunkenness, (he must only mean the German states, for we have several acts of parliament against it in England), and that it is only punished by contempt. "Custom," says he, "that tyrant of the human race, not only permits it, but in some sort authorizes the practice, insomuch that we see priests and ministers of the Church ascend the pulpit in a state of intoxication, judges seat themselves upon the benches, physicians attend their patients, and others attempt to perform the different avocations of life, in the same disgraceful state." - Physic. Sacr., vol. iii., p. 64. This is a horrible picture of German manners; and while we deplore the extensive ravages made by this vice, and the disgrace with which its votaries are overwhelmed, we have reason to thank God that it very rarely has ever appeared in the pulpit, and perhaps was never once seen upon the bench, in our own country. Having delivered the law against drinking wine, Moses proceeds to deliver a series of ordinances, all well calculated to prevent the Israelites from mixing with the surrounding nations, and consequently from being contaminated by their idolatry. In Leviticus 11 he treats of unclean Meats. In Lev 12:1-8, 13, 14, and 15, he treats of unclean Persons, Garments, and Dwellings. In Leviticus 16 he treats of the uncleanness of the Priests and the People, and prescribes the proper expiations and sacrifices for both. In Leviticus 17 he continues the subject, and gives particular directions concerning the mode of offering, etc. In Leviticus 18 he treats of unclean matrimonial connections. In Leviticus 19 he repeats sundry laws relative to these subjects, and introduces some new ones. In Leviticus 20 he mentions certain uncleannesses practiced among the idolatrous nations, and prohibits them on pain of death. In Leviticus 21 he treats of the mourning, marriages, and personal defects of the priests, which rendered them unclean. And in Leviticus 22 he speaks of unclean sacrifices, or such as should not be offered to the Lord. After this, to the close of the book, many important and excellent political and domestic regulations are enjoined, the whole forming an eccleslastico-political system superior to any thing the world ever saw. Bishop Wilson very properly observes that, "by these laws of clean and unclean animals, etc., God did keep this people separated from the idolatrous world: and this is a standing proof, even to the present day, of the Divine authority of these Scriptures; for no power or art of man could have obliged so great and turbulent a nation to submit to such troublesome precepts as the Jews always have submitted to, had they not been fully convinced, from the very first, that the command was from God, and that it was to be obeyed at the peril of their souls."

Speak unto the children of Israel, saying,.... For to them only belong the following laws, and not unto the Gentiles, as Jarchi rightly observes; these were parts of the ceremonial law, which was peculiarly given to them, and lay, among other things, in meats and drinks, and now abolished; for it is not what goes into a man that defiles him; nor is anything common or unclean of itself, but every creature of God is good if received with thanksgiving. The sons of Noah had free liberty, without any restraint or limitation, of using for food any living creature that moved upon the face of the earth; in the choice of which they were left to exercise their reason and judgment, and is the case with us now; but as men have not so nice a smell as some animals have, and cannot distinguish by their senses so well as they what food is most wholesome, which makes the exercise of their reason and judgment necessary, and the people of the Jews being a special people, and for whom the Lord had a peculiar regard; for the sake of their health, and to preserve them from diseases they were subject to, such as the leprosy and others, and to direct them to what was most salubrious and healthful, gave them the following laws; and which, though they are not obligatory upon us, yet may be a direction to us, in the use of what may be most suitable and proper food for us, the difference of climates, and of the constitutions of men's bodies, being considered: not that we are to suppose, that the case of health was the only reason of delivering out these laws to the children of Israel, for other ends, besides that, may be thought to be had in view; as to assert his sovereign right to the creatures, and his disposal of them to them according to his will and pleasure; to lay a restraint on their appetites, to prevent luxury, and to teach them self denial, and compliance with his will; as also to keep them the more from the company and conversation of the Gentiles, by whom they otherwise might be led into idolatry; and to give them an aversion to their idols, to whom the creatures forbidden them to eat, many of them were either now or would be sacred to them; and chiefly to excite to a care for purity, both inward and outward, and create in the man abhorrence of those vices which may be signified by the ill qualities of several of the creatures; and to instruct them in the difference between holy and unholy persons, with whom they should or should not have communion; see Act 10:11.

these are the beasts that ye shall eat among all the beasts that are on the earth; they are not particularly mentioned here, but they are in Deu 14:4 and they are these ten; the ox, the sheep, and the goat, the hart, and the roebuck, and the fallow deer, and the wild goat, and the pygarg, and the wild ox, and the chamois; of all which; see Gill on Deu 14:4, Deu 14:5, here only some general things are observed to describe them by, as follow.
