Here is, I. A law to preserve the honour of the marriage-bed, that it should not be unseasonably used (Lev 18:19), nor invaded by an adulterer, Lev 18:20.

II.A law against that which was the most unnatural idolatry, causing their children to pass through the fire to Moloch, Lev 18:21. Moloch (as some think) was the idol in and by which they worshipped the sun, that great fire of the world; and therefore in the worship of it they made their own children either sacrifices to this idol, burning them to death before it, or devotees to it, causing them to pass between two fires, as some think, or to be thrown through one, to the honour of this pretended deity, imagining that the consecrating of but one of their children in this manner to Moloch would procure good fortune for all the rest of their children. Did idolaters thus give their own children to false gods, and shall we think any thing too dear to be dedicated to, or to be parted with for, the true God? See how this sin of Israel (which they were afterwards guilty of, notwithstanding this law) is aggravated by the relation which they and their children stood in to God. Eze 16:20, Thou hast taken thy sons and thy daughters, whom thou hast borne unto me, and these thou hast sacrificed. Therefore it is here called profaning the name of their God; for it looked as if they thought they were under greater obligations to Moloch than to Jehovah; for to him they offered their cattle only, but to Moloch their children.

III.A law against unnatural lusts, sodomy and bestiality, sins not to be named nor thought of without the utmost abhorrence imaginable, Lev 18:22, Lev 18:23. Other sins level men with the beasts, but these sink them much lower. That ever there should have been occasion for the making of these laws, and that since they are published they should ever have been broken, is the perpetual reproach and scandal of human nature; and the giving of men up to these vile affections was frequently the punishment of their idolatries; so the apostle shows, Rom 1:24.

IV.Arguments against these and the like abominable wickednesses. He that has an indisputable right to command us, yet because he will deal with us as men, and draw with the cords of a man, condescends to reason with us. 1. Sinners defile themselves with these abominations: Defile not yourselves in any of these things, Lev 18:24. All sin is defiling to the conscience, but these are sins that have a peculiar turpitude in them. Our heavenly Father, in kindness to us, requires of us that we keep ourselves clean, and do not wallow in the dirt. 2. The souls that commit them shall be cut off, Lev 18:29. And justly; for, if any man defile the temple of God, him shall God destroy, Co1 3:17. Fleshly lusts war against the soul, and will certainly be the ruin of it if God's mercy and grace prevent not. 3. The land is defiled, Lev 18:25. If such wickednesses as these be practised and connived at, the land is thereby made unfit to have God's tabernacle in it, and the pure and holy God will withdraw the tokens of his gracious presence from it. It is also rendered unwholesome to the inhabitants, who are hereby infected with sin and exposed to plagues and it is really nauseous and loathsome to all good men in it, as the wickedness of Sodom was to the soul of righteous Lot. 4. These have been the abominations of the former inhabitants, v, 24, 27. Therefore it was necessary that these laws should be made, as antidotes and preservatives from the plague are necessary when we go into an infected place. And therefore they should not practise any such things, because the nations that had practised them now lay under the curse of God, and were shortly to fall by the sword of Israel. They could not but be sensible how odious those people had made themselves who wallowed in this mire, and how they stank in the nostrils of all good men; and shall a people sanctified and dignified as Israel was make themselves thus vile? When we observe how ill sin looks in others we should use this as an argument with ourselves with the utmost care and caution to preserve our purity. 5. For these and the like sins the Canaanites were to be destroyed; these filled the measure of the Amorites' iniquity (Gen 15:16), and brought down that destruction of so many populous kingdoms which the Israelites were now shortly to be not only the spectators, but the instruments of: Therefore I do visit the iniquity thereof upon it, Lev 18:25. Note, The tremendous judgments of God, executed on those that are daringly profane and atheistical, are intended as warnings to those who profess religion to take heed of every thing that has the least appearance of, or tendency towards, profaneness or atheism. Even the ruin of the Canaanites is an admonition to the Israelites not to do like them. Nay, to show that not only the Creator is provoked, but the creation burdened, by such abominations as these, it is added (Lev 18:25), The land itself vomiteth out her inhabitants. The very ground they went upon did, as it were, groan under them, and was sick of them, and not easy till it had discharged itself of these enemies of the Lord, Isa 1:24. This bespeaks the extreme loathsomeness of sin; sinful man indeed drinks in iniquity like water, but the harmless part of the creation even heaves at it, and rises against it. Many a house and many a town have spued out the wicked inhabitants, as it were, with abhorrence, Rev 3:16. Therefore take heed, saith God, that the land spue not you out also, Lev 18:28. It was secured to them, and entailed upon them, and yet they must expect that, if they made the vices of the Canaanites their own, with their land their fate would be the same. Note, Wicked Israelites are as abominable to God as wicked Canaanites, and more so, and will be as soon spued out, or sooner. Such a warning as was here given to the Israelites is given by the apostle to the Gentile converts, with reference to the rejected Jews, in whose room they were substituted (Rom 11:19, etc.); they must take heed of falling after the same example of unbelief, Heb 4:11. Apply it more generally; and let it deter us effectually from all sinful courses to consider how many they have been the ruin of. Lay the ear of faith to the gates of the bottomless pit, and hear the doleful shrieks and outcries of damned sinners, whom earth has spued out and hell has swallowed, that find themselves undone, for ever undone, by sin; and tremble lest this be your portion at last. God's threatenings and judgments should frighten us from sin.

V.The chapter concludes with a sovereign antidote against this infection: Therefore you shall keep my ordinance that you commit not any one of these abominable customs, Lev 18:30. This is the remedy prescribed. Note, 1. Sinful customs are abominable customs, and their being common and fashionable does not make them at all the less abominable nor should we the less abominate them, but the more; because the more customary they are the more dangerous they are. 2. It is of pernicious consequence to admit and allow of any one sinful custom, because one will make way for many, Uno absurdo dato, mille sequuntur - Admit but a single absurdity, you invite a thousand. The way of sin is downhill. 3. A close and constant adherence to God's ordinances is the most effectual preservative from the infection of gross sin. The more we taste of the sweetness and feel of the power of holy ordinances the less inclination we shall have to the forbidden pleasures of sinners' abominable customs. It is the grace of God only that will secure us, and that grace is to be expected only in the use of the means of grace. Nor does God ever leave any to their own hearts' lusts till they have first left him and his institutions.

Pass through the fire to Molech - The name of this idol is mentioned for the first time in this place. As the word מלח molech or melech signifies king or governor, it is very likely that this idol represented the sun; and more particularly as the fire appears to have been so much employed in his worship. There are several opinions concerning the meaning of passing through the fire to Molech.

1.Some think that the semen humanum was offered on the fire to this idol.

2.Others think that the children were actually made a burnt-offering to him.

3.But others suppose the children were not burnt, but only passed through the fire, or between two fires, by way of consecration to him.

That some were actually burnt alive to this idol several scriptures, according to the opinion of commentators, seem strongly to intimate; see among others, Psa 106:38; Jer 7:31, and Eze 23:37-39. That others were only consecrated to his service by passing between two fires the rabbins strongly assert; and if Ahaz had but one son, Hezekiah, (though it is probable he had others, see Ch2 28:3), he is said to have passed through the fire to Molech, Kg2 16:3, yet he succeeded his father in the kingdom, Kg2 18:1, therefore this could only be a consecration, his idolatrous father intending thereby to initiate him early into the service of this demon. See Clarke's note on Lev 20:2.

And thou shalt not let any of thy seed pass through the fire to Molech,.... The name of an image or idol, according to Aben Ezra, who observes, that their wise men interpret it as a general name for everyone whom they made to reign over them; and it is right, he says, that it is the abomination of the children of Ammon, and so the same with Milcom, Kg1 11:5; and with Baal, as appears from Jer 32:35; and they are both of much the same signification, the one signifies a king, the other a lord; and perhaps is the same with the Melicarthus of Sanchoniatho (y), who is also Hercules; to whom Pliny says (z) that the Phoenicians offered human sacrifices every year: of Molech; see Gill on Jer 7:31, Amo 1:13; by "seed" is meant children and offspring; and because the word "fire" is not in the original text, some, as Aben Ezra observes, explain the phrase, "let to pass through", of their causing them to pass from the law of God to the religion of Molech, or of devoting them to his service and worship; but the word "fire" is rightly supplied, as it may be from Deu 18:10; and the same writer says, the phrase to pass through is the same as to burn; but though this they sometimes did, even burn their infants, and sacrificed them to idols, Ch2 28:3; yet this seems to be something short of that, and to be done in the manner, as Jarchi and other Jewish writers (a) relate; who say, the father delivered his son to the priests (of Molech) and they made two great fires, and caused the son to pass on foot between the two fires, which was a kind of a lustration, and so of a dedication of them to the idol; though it must be owned that both were done; yea, that both the phrases of passing through the fire, and of burning, are used promiscuously of the same, see Kg2 16:3; compared with Ch2 28:3 and also Eze 16:20; and they might be both done at different times, or the one previous and in order to the other; and perhaps they might cause the child so often and so long to pass through the fire, as that at last it was burnt and destroyed:

neither shall thou profane the name of thy God; who had given them children, and to whom they ought to have devoted them, and in whose service they should have trained them up to the honour of his name; but instead of that profaned it, by the above idolatrous and cruel usages:

I am the Lord; who would avenge such a profanation of his name.

(y) Apud, Euseb. Praepar. Evangel. l. 1. p. 38. (z) Nat. Hist. l. 36. c. 5. (a) Ben Melech in loc. Kimchii Sepher Shorash. rad.

thou shalt not let any of thy seed pass through the fire to Molech, &c.--Molech, or Moloch, which signifies "king," was the idol of the Ammonites. His statue was of brass, and rested on a pedestal or throne of the same metal. His head, resembling that of a calf, was adorned with a crown, and his arms were extended in the attitude of embracing those who approached him. His devotees dedicated their children to him; and when this was to be done, they heated the statue to a high pitch of intensity by a fire within, and then the infants were either shaken over the flames, or passed through the ignited arms, by way of lustration to ensure the favor of the pretended deity. The fire-worshippers asserted that all children who did not undergo this purifying process would die in infancy; and the influence of this Zabian superstition was still so extensively prevalent in the days of Moses, that the divine lawgiver judged it necessary to prohibit it by an express statute.

neither shalt thou profane the name of thy God--by giving it to false or pretended divinities; or, perhaps, from this precept standing in close connection with the worship of Molech, the meaning rather is, Do not, by devoting your children to him, give foreigners occasion to blaspheme the name of your God as a cruel and sanguinary deity, who demands the sacrifice of human victims, and who encourages cruelty in his votaries.
