Ver. 1-21. God, having chosen Israel for his own, separated them from the nations, adopted them as his children, and designed them for his glory, has a right to expect from them that they should answer these purposes of his grace, and approve themselves a holy people before him. And this must appear, 1. In their mournings, when all inordinate sorrow must be avoided; and every superstitious practice which the Gentiles used must be abhorred. Note; (1.) We are not forbidden to mourn for the dead; but to express immoderate sorrow would be the proof of idolatrous attachment to the creature, and a dishonour to God. (2.) As our bodies are not our own, but bought with a price, we must glorify God in them, and not disfigure or deform that temple where he is pleased to take up his abode. 2. In their meat. Though many of the forbidden beasts, or fish, or fowl, may, in themselves, be good for food, and allowable to others, yet God will lay them under particular restraints, to prevent their mingling with the heathen. There is enough permitted them to remove every occasion of just complaint, if their perverse appetites did not enslave them. Note; Those who are not satisfied with the lawful gratifications that God allows, never will be satisfied in the gratification of their lawless lusts. The above observances are purely judaical, and the reason of them has now ceased; but the separation from evil, and the dedication of ourselves to God, which these signified, still remain obligatory on every christian.
Deuteronomy 14:1-21
1 Ye are the children of the LORD your God: ye shall not cut yourselves, nor make any baldness between your eyes for the dead.
2 For thou art an holy people unto the LORD thy God, and the LORD hath chosen thee to be a peculiar people unto himself, above all the nations that are upon the earth.
3 Thou shalt not eat any abominable thing.
4 These are the beasts which ye shall eat: the ox, the sheep, and the goat,
5 The hart, and the roebuck, and the fallow deer, and the wild goat, and the pygarg, and the wild ox, and the chamois.
6 And every beast that parteth the hoof, and cleaveth the cleft into two claws, and cheweth the cud among the beasts, that ye shall eat.
7 Nevertheless these ye shall not eat of them that chew the cud, or of them that divide the cloven hoof; as the camel, and the hare, and the coney: for they chew the cud, but divide not the hoof; therefore they are unclean unto you.
8 And the swine, because it divideth the hoof, yet cheweth not the cud, it is unclean unto you: ye shall not eat of their flesh, nor touch their dead carcase.
9 These ye shall eat of all that are in the waters: all that have fins and scales shall ye eat:
10 And whatsoever hath not fins and scales ye may not eat; it is unclean unto you.
11 Of all clean birds ye shall eat.
12 But these are they of which ye shall not eat: the eagle, and the ossifrage, and the ospray,
13 And the glede, and the kite, and the vulture after his kind,
14 And every raven after his kind,
15 And the owl, and the night hawk, and the cuckow, and the hawk after his kind,
16 The little owl, and the great owl, and the swan,
17 And the pelican, and the gier eagle, and the cormorant,
18 And the stork, and the heron after her kind, and the lapwing, and the bat.
19 And every creeping thing that flieth is unclean unto you: they shall not be eaten.
20 But of all clean fowls ye may eat.
21 Ye shall not eat of any thing that dieth of itself: thou shalt give it unto the stranger that is in thy gates, that he may eat it; or thou mayest sell it unto an alien: for thou art an holy people unto the LORD thy God. Thou shalt not seethe a kid in his mother's milk.
