Moses here tells the people of Israel,
I. How God had dignified them, as a peculiar people, with three distinguishing privileges, which were their honour, and figures of those spiritual blessings in heavenly things with which God has in Christ blessed us. 1. Here is election: The Lord hath chosen thee, v. 2. Not for their own merit, nor for any good works foreseen, but because he would magnify the riches of his power and grace among them. He did not choose them because they were by their own dedication and subjection a peculiar people to him above other nations, but he chose them that they might be so by his grace; and thus were believers chosen, Eph. i. 4. 2. Here is adoption (v. 1): "You are the children of the Lord your God, formed by him into a people, owned by him as his people, nay, his family, a people near unto him, nearer than any other." Israel is my son, my first-born; not because he needed children, but because they were orphans, and needed a father. Every Israelite is indeed a child of God, a partaker of his nature and favour, his love and blessing Behold what manner of love the Father has bestowed upon us! 3. Here is sanctification (v. 2): "Thou art a holy people, separated and set apart for God, devoted to his service, designed for his praise, governed by a holy law, graced by a holy tabernacle, and the holy ordinances relating to it." God's people are under the strongest obligations to be holy, and, if they are holy, are indebted to the grace of God that makes them so. The Lord has set them apart for himself, and qualified them for his service and the enjoyment of him, and so has made them holy to himself.
II. How they ought to distinguish themselves by a sober singularity from all the nations that were about them. And, God having thus advanced them, let not them debase themselves by admitting the superstitious customs of idolaters, and, by making themselves like them, put themselves upon the level with them. Be you the children of the Lord your God; so the Seventy read it, as a command, that is, "Carry yourselves as becomes the children of God, and do nothing to disgrace the honour and forfeit the privileges of the relation." In two things particularly they must distinguish themselves:--
1. In their mourning: You shall not cut yourselves, v. 1. This forbids (as some think), not only their cutting themselves at their funerals, either to express their grief or with their own blood to appease the infernal deities, but their wounding and mangling themselves in the worship of their gods, as Baal's prophets did (1 Kings xviii. 28), or their marking themselves by incisions in their flesh for such and such deities, which in them, above any, would be an inexcusable crime, who in the sign of circumcision bore about with them in their bodies the marks of the Lord Jehovah. So that, (1.) They are forbidden to deform or hurt their own bodies upon any account. Methinks this is like a parent's change to his little children, that are foolish, careless, and wilful, and are apt to play with knives: Children, you shall not cut yourselves. This is the intention of those commands which oblige us to deny ourselves; the true meaning of them, if we understood them aright, would appear to be, Do yourselves no harm. And this also is the design of those providences which most cross us, to remove from us those things by which we are in danger of doing ourselves harm. Knives are taken from us, lest we should cut ourselves. Those that are dedicated to God as a holy people must do nothing to disfigure themselves; the body is for the Lord, and is to be used accordingly. (2.) They are forbidden to disturb and afflict their own minds with inordinate grief for the loss of near and dear relations: "You shall not express or exasperate you sorrow, even upon the most mournful occasions, by cutting yourselves, and making baldness between your eyes, like men enraged, or resolvedly hardened in sorrow for the dead, as those that have no hope," 1 Thess. iv. 13. It is an excellent passage which Mr. Ainsworth here quotes from one of the Jewish writers, who understands this as a law against immoderate grief for the death of our relations. If your father (for instance) die, you shall not cut yourselves, that is, you shall not sorrow more than is meet, for you are not fatherless, you have a Father, who is great, living, and permanent, even the holy blessed God, whose children you are, v. 1. But an infidel (says he), when his father dies, hath no father that can help him in time of need; for he hath said to a stock, Thou art my father, and to a stone, Thou hast brought me forth (Jer. ii. 27); therefore he weeps, cuts himself, and makes himself bald. We that have a God to hope in, and a heaven to hope for, must bear up ourselves with that hope under every burden of this kind.
2. They must be singular in their meat. Observe,
(1.) Many sorts of flesh which were wholesome enough, and which other people did commonly eat, they must religiously abstain from as unclean. This law we had before Lev. xi. 2, where it was largely opened. It seems plainly, by the connection here, to be intended as a mark of peculiarity; for their observance of it would cause them to be taken notice of in all mixed companies as a separate people, and would preserve them from mingling themselves with, and conforming themselves to, their idolatrous neighbours. [1.] Concerning beasts, here is a more particular enumeration of those which they were allowed to eat then was in Leviticus, to show that they had no reason to complain of their being restrained from eating swines' flesh, and hares, and rabbits (which were all that were then forbidden, but are now commonly used), when they were allowed so great a variety, not only of that which we call butcher's meat (v. 4), which alone was offered in sacrifice, but of venison, which they had great plenty of in Canaan, the hart, and the roe-buck, and the fallow deer (v. 5), which, though never brought to God's altar, was allowed them at their own table. See ch. xii. 22. When of all these (as Adam of every tree of the garden) they might freely eat, those were inexcusable who, to gratify a perverse appetite, or (as should seem) in honour of their idols, and in participation of their idolatrous sacrifices, ate swines' flesh, and had broth of abominable things (made so by this law) in their vessels, Isa. lxv. 4. [2.] Concerning fish there is only one general rule given, that whatsoever had not fins and scales (as shell-fish and eels, besides leeches and other animals in the water that are not proper food) was unclean and forbidden, v. 9, 10. [3.] No general rule is given concerning fowl, but those are particularly mentioned that were to be unclean to them, and there are few or none of them which are here forbidden that are now commonly eaten; and whatsoever is not expressly forbidden is allowed, v. 11-20. Of all clean fowls you may eat. [4.] They are further forbidden, First, To eat the flesh of any creature that died of itself, because the blood was not separated from it, and, besides the ceremonial uncleanness which it lay under (from Lev. xi. 39), it is not wholesome food, nor ordinarily used among us, except by the poor. Secondly, To seethe a kid in its mother's milk, either to gratify their own luxury, supposing it a dainty bit, or in conformity to some superstitious custom of the heathen. The Chaldee paraphrasts read it, Thou shalt not eat flesh--meats and milk--meats together; and so it would forbid the use of butter as sauce to any flesh.
(2.) Now as to all these precepts concerning their food, [1.] It is plain in the law itself that they belonged only to the Jews, and were not moral, nor of perpetual use, because not of universal obligation; for what they might not eat themselves they might give to a stranger, a proselyte of the gate, that had renounced idolatry, and therefore was permitted to live among them, though not circumcised; or they might sell it to an alien, a mere Gentile, that came into their country for trade, but might not settle it, v. 21. They might feed upon that which an Israelite might not touch, which is a plain instance of their peculiarity, and their being a holy people. [2.] It is plain in the gospel that they are now antiquated and repealed. For every creature of God is good, and nothing now to be refused, or called common and unclean, 1 Tim. iv. 4.
