Leviticus 18: Summary and Commentary

Verse 1

18:1–20:27 Chapters 18 and 20 primarily discuss sexual matters, warning against engaging in pagan practices both religious and secular. These chapters bracket exhortations to pursue holiness in everyday life (ch 19).

Verse 2

18:2 Many Near Eastern treaties began with the name and titles of the ruler who was drawing up the treaty. The phrase I am the Lord your God gives the name of the Great King, Yahweh (English the Lord), followed by his title, your God (see also Exod 20:2; Deut 5:6). These words were an abbreviated way to invoke Israel’s covenant with God and all that it implied. By reminding the people that they were the Lord’s, these words carried an authority that required a response (Lev 11:44; 18:4-5). Chapter 18 begins and ends (18:30) with these words, and they appear frequently throughout chs 19–26.

Verse 4

18:4-5 regulations . . . decrees: The Bible anticipated that the courts would need to interpret the laws that God had provided to apply them to different circumstances. Such interpretations became case laws; the body of these court decisions was called mishpatim in Hebrew (cp. “decrees” in 10:11). • Paul alludes to these verses in Rom 10:5 and Gal 3:12, where he contrasts the “way of faith” with the “way of law.”

Verse 6

18:6-7 have sexual relations with: Literally to uncover the nakedness of. Similar regulations in ch 20 use the Hebrew word shakab (“lie with”), a word frequently used to indicate an improper sexual relationship.

Verse 7

18:7-8 violate your father: The Hebrew text here equates having sexual relations with your mother or any of your father’s wives with having sexual relations with him (cp. Gen 35:22; 49:4; see also 1 Cor 5:1). The husband and his wife were “two united into one” (Gen 2:24; cp. Eph 5:29). Always in the background of these commands are the commands to honor your parents (Lev 20:9; Exod 20:12) and, by extension, other members of the family (see also study note on Lev 20:17).

18:7 She is your mother: Incest was prohibited because of the disruption it created in families, so the commands concerning this sin included close relatives not necessarily related by blood. Incest was a serious crime because it brought competition and chaos into the family structure. It threatened the safety of the home by violating a family’s appropriate intimacy and the sense of belonging shared by its members. • The commands were directly addressed to the male, even though the female could be older (such as one’s mother). The male, especially if he was the head of the household or the firstborn, wielded more power than the female; with this position came the responsibility to use that power lawfully. In addition, the male was more likely to be the sexual aggressor in an illicit sexual union, although this was not always the case (e.g., Gen 39:6-18).

Verse 9

18:9 Sexual relations with a full sister dishonored both parents, and relations with a half sister dishonored one parent.

Verse 12

18:12-13 your father’s sister . . . mother’s sister: These actions would dishonor your father or mother.

Verse 14

18:14 Having sexual relations with your aunt would dishonor your uncle. In turn, this would also dishonor your father (see 20:20).

Verse 15

18:15 Just as having sexual relations with your father’s wife would dishonor your father, having sexual relations with your daughter-in-law would dishonor your son. The law called for daughters-in-law to be treated like natural daughters (Exod 21:9; cp. Gen 38:1-30).

Verse 16

18:16 Sexual relations with your sister-in-law would be adulterous and disgrace your brother. The exception was the law of levirate marriage (see Deut 25:5-10), which called for a man to marry his brother’s widow in order to produce an heir who was considered the dead brother’s son.

Verse 17

18:17 As with all examples listed in ch 18, marrying a woman together with her daughter or granddaughter was prohibited because of the disruption it would cause in the family order. It would violate the intimacy of the family group by forcing a wife to compete for her husband’s affections against a much younger woman. The penalty for this act was death by burning (20:14).

Verse 18

18:18 The word rivals (Hebrew tsarah) vividly describes the relationship between Leah and Rachel (Gen 29:16–30:24) and Hannah and Peninnah (1 Sam 1:6); in both cases, the fellow wives were driven to bitter rivalry for their husband’s affections.

Verse 20

18:20 The Hebrew word translated defile yourself could be more literally translated to become ceremonially unclean. • Sexual intercourse with a neighbor’s wife or any married woman defined adultery in the Old Testament. Breaking this law was punishable by death (Deut 22:22). Like incest, adultery threatened the integrity and security of the home and family. In this case, it violated the covenant of marriage and divided the adulterer’s affection between his spouse and his mistress.

Verse 21

18:21 Molech was the national god of the Ammonites (1 Kgs 11:7). This god was later worshiped by Israel during times of apostasy (2 Kgs 23:10; Jer 32:35). Molech probably appears in this list because Molech worship was associated with sexual sins; it seems to have included child sacrifice as well. • To bring shame on (literally blaspheme, profane) the name of your God meant using the name of the Lord as though it were not holy, such as in a false oath (Lev 19:12) or in the worship of a false god (Ezek 20:39).

Verse 22

18:22 In Gen 1:31, God pronounced all things good. This yielded a theology of the created order where good is defined by what God created and by the way he intended it to function. Part of this “good” was the creation of woman as man’s companion (Gen 2:22-24). Marriage forms a microcosm of the human race, which stands as the corporate bearer of God’s image. Sin, introduced by the Fall (Gen 3), disrupted the created order. Homosexuality is but one example of sinful violation of God’s order; it is tied to the rejection of God by fallen humanity (Rom 1:25-32). • The Hebrew word translated detestable (to‘ebah) indicates strong disapproval and disgust (Lev 20:13; see also 18:26-30).

Verse 23

18:23 Like homosexuality, bestiality is a violation of the natural order (see study note on 18:22). • The phrase perverse act referred not only to a violation, but to a confusion of the order God created because it broke down clear boundaries that he had established.

Verse 24

18:24-25 any of these ways: Pagan worship (18:21), homosexuality (18:22), and bestiality (18:23). • The land was so nauseated by Canaanite practices that it would dramatically vomit them out (see 18:28).

Verse 28

18:28 Just as the land would vomit out the Canaanites, it would also vomit out the Israelites if they acted like the Canaanites (see study note on 18:24-25). This came to pass with the destruction and exile of the northern kingdom by the Assyrians in 722 BC (2 Kgs 17:6) and when the Babylonians destroyed and exiled Judah in 586 BC (2 Kgs 25:8-21).

Verse 1

After divers ceremonial institutions, God here returns to the enforcement of moral precepts. The former are still of use to us as types, the latter still binding as laws. We have here, 1. The sacred authority by which these laws are enacted: I am the Lord your God (Lev 18:1, Lev 18:4, Lev 18:30), and I am the Lord, Lev 18:5, Lev 18:6, Lev 18:21. "The Lord, who has a right to rule all; your God, who has a peculiar right to rule you." Jehovah is the fountain of being, and therefore the fountain of power, whose we are, whom we are bound to serve, and who is able to punish all disobedience. "Your God to whom you have consented, in whom you are happy, to whom you lie under the highest obligations imaginable, and to whom you are accountable." 2. A strict caution to take heed of retaining the relics of the idolatries of Egypt, where they had dwelt, and of receiving the infection of the idolatries of Canaan, whither they were now going, Lev 18:3. Now that God was by Moses teaching them his ordinances there was aliquid dediscendum - something to be unlearned, which they had sucked in with their milk in Egypt, a country noted for idolatry: You shall not do after the doings of the land of Egypt. It would be the greatest absurdity in itself to retain such an affection for their house of bondage as to be governed in their devotions by the usages of it, and the greatest ingratitude to God, who had so wonderfully and graciously delivered them. Nay, as if governed by a spirit of contradiction, they would be in danger, even after they had received these ordinances of God, of admitting the wicked usages of the Canaanites and of inheriting their vices with their land. Of this danger they are here warned, You shall not walk in their ordinances. Such a tyrant is custom that their practices are called ordinances, and they became rivals even with God's ordinances, and God's professing people were in danger of receiving law from them. 3. A solemn charge to them to keep God's judgments, statutes, and ordinances, Lev 18:4, Lev 18:5. To this charge, and many similar ones, David seems to refer in the many prayers and professions he makes relating to God's laws in the 119th Psalm. Observe here, (1.) The great rule of our obedience - God's statutes and judgments. These we must keep to walk therein. We must keep them in our books, and keep them in our hands, that we may practise them in our hearts and lives. Remember God's commandments to do them, Psa 103:18. We must keep in them as our way to travel in, keep to them as our rule to work by, keep them as our treasure, as the apple of our eye, with the utmost care and value. (2.) The great advantage of our obedience: Which if a man do, he shall live in them, that is, "he shall be happy here and hereafter." We have reason to thank God, [1.] That this is still in force as a promise, with a very favourable construction of the condition. If we keep God's commandments in sincerity, though we come short of sinless perfection, we shall find that the way of duty is the way of comfort, and will be the way to happiness. Godliness has the promise of life, Ti1 4:8. Wisdom has said, Keep my commandments and live: and if through the Spirit we mortify the deeds of the body (which are to us as the usages of Egypt were to Israel) we shall live. [2.] That it is not so in force in the nature of a covenant as that the least transgression shall for ever exclude us from this life. The apostle quotes this twice as opposite to the faith which the gospel reveals. It is the description of the righteousness which is by the law, the man that doeth them shall live en autois - in them (Rom 10:5), and is urged to prove that the law is not of faith, Gal 3:12. The alteration which the gospel has made is in the last word: still the man that does them shall live, but not live in them; for the law could not give life, because we could not perfectly keep it; it was weak through the flesh, not in itself; but now the man that does them shall live by the faith of the Son of God. He shall owe his life to the grace of Christ, and not to the merit of his own works; see Gal 3:21, Gal 3:22. The just shall live, but they shall live by faith, by virtue of their union with Christ, who is their life.

Verse 6

These laws relate to the seventh commandment, and, no doubt, are obligatory on us under the gospel, for they are consonant to the very light and law of nature: one of the articles, that of a man's having his father's wife, the apostle speaks of as a sin not so much as named among the Gentiles, Co1 5:1. Though some of the incests here forbidden were practised by some particular persons among the heathen, yet they were disallowed and detested, unless among those nations who had become barbarous, and were quite given up to vile affections. Observe,

I. That which is forbidden as to the relations here specified is approaching to them to uncover their nakedness, Lev 18:6.

1. It is chiefly intended to forbid the marrying of any of these relations. Marriage is a divine institution; this and the sabbath, the eldest of all, of equal standing with man upon the earth: it is intended for the comfort of human life, and the decent and honourable propagation of the human race, such as became the dignity of man's nature above that of the beasts. It is honourable in all, and these laws are for the support of the honour of it. It was requisite that a divine ordinance should be subject to divine rules and restraints, especially because it concerns a thing wherein the corrupt nature of man is as apt as in any thing to be wilful and impetuous in its desires, and impatient of check. Yet these prohibitions, besides their being enacted by an incontestable authority, are in themselves highly reasonable and equitable. (1.) By marriage two were to become one flesh, therefore those that before were in a sense one flesh by nature could not, without the greatest absurdity, become one flesh by institution; for the institution was designed to unite those who before were not united. (2.) Marriage puts an equality between husband and wife. "Is she not thy companion taken out of thy side?" Therefore, if those who before were superior and inferior should intermarry (which is the case in most of the instances here laid down), the order of nature would be taken away by a positive institution, which must by no means be allowed. The inequality between master and servant, noble and ignoble, is founded in consent and custom, and there is no harm done if that be taken away by the equality of marriage; but the inequality between parents and children, uncles and nieces, aunts and nephews, either by blood or marriage, is founded in nature, and is therefore perpetual, and cannot without confusion be taken away by the equality of marriage, the institution of which, though ancient, is subsequent to the order of nature. (3.) No relations that are equals are forbidden, except brothers and sisters, by the whole blood or half blood, or by marriage; and in this there is not the same natural absurdity as in the former, for Adam's sons must of necessity have married their own sisters; but it was requisite that it should be made by a positive law unlawful and detestable, for the preventing of sinful familiarities between those that in the days of their youth are supposed to live in a house together, and yet cannot intermarry without defeating one of the intentions of marriage, which is the enlargement of friendship and interest. If every man married his own sister (as they would be apt to do from generation to generation if it were lawful), each family would be a world to itself, and it would be forgotten that we are members one of another. It is certain that this has always been looked upon by the more sober heathen as a most infamous and abominable thing; and those who had not this law yet were herein a law to themselves. The making use of the ordinance of marriage for the patronizing of incestuous mixtures is so far from justifying them, or extenuating their guilt, that it adds the guilt of profaning an ordinance of God, and prostituting that to the vilest of purposes which was instituted for the noblest ends. But,

2. Uncleanness, committed with any of these relations out of marriage, is likewise, without doubt, forbidden here, and no less intended than the former: as also all lascivious carriage, wanton dalliance, and every thing that has the appearance of this evil. Relations must love one another, and are to have free and familiar converse with each other, but it must be with all purity; and the less it is suspected of evil by others the more care ought the persons themselves to take that Satan do not get advantage against them, for he is a very subtle enemy, and seeks all occasions against us.

II. The relations forbidden are most of them plainly described; and it is generally laid down as a rule that what relations of a man's own he is bound up from marrying the same relations of his wife he is likewise forbidden to marry, for they two are one. That law which forbids marrying a brother's wife (Lev 18:16) had an exception peculiar to the Jewish state, that, if a man died without issue, his brother or next of kin should marry the widow, and raise up seed to the deceased (Deu 25:5), for reasons which held good only in that commonwealth; and therefore now that those reasons have ceased the exception ceases, and the law is in force, that a man must in no case marry his brother's widow. That article (Lev 18:18) which forbids a man to take a wife to her sister supposes a connivance at polygamy, as some other laws then did (Exo 21:10; Deu 21:15), but forbids a man's marrying two sisters, as Jacob did, because between those who had before been equal there would be apt to arise greater jealousies and animosities than between wives that were not so nearly related. If the sister of the wife be taken for the concubine, or secondary wife, nothing can be more vexing in her life, or as long as she lives.

Verse 19

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.

Verse 5

Ye shall therefore keep my statutes, and my judgments: which if a man do, he shall live in them—A special blessing was promised to the Israelites on condition of their obedience to the divine law; and this promise was remarkably verified at particular eras of their history, when pure and undefiled religion prevailed among them, in the public prosperity and domestic happiness enjoyed by them as a people. Obedience to the divine law always, indeed, ensures temporal advantages; and this, doubtless, was the primary meaning of the words, "which if a man do, he shall live in them." But that they had a higher reference to spiritual life is evident from the application made of them by our Lord (Luk 10:28) and the apostle (Rom 10:2).

Verse 6

None of you shall approach to any that is near of kin to him—Very great laxity prevailed amongst the Egyptians in their sentiments and practice about the conjugal relation, as they not only openly sanctioned marriages between brothers and sisters, but even between parents and children. Such incestuous alliances Moses wisely prohibited, and his laws form the basis upon which the marriage regulations of this and other Christian nations are chiefly founded. This verse contains a general summary of all the particular prohibitions; and the forbidden intercourse is pointed out by the phrase, "to approach to." In the specified prohibitions that follow, all of which are included in this general summary, the prohibited familiarity is indicated by the phrases, to "uncover the nakedness" [Lev 18:12-17], to "take" [Lev 18:17-18], and to "lie with" [Lev 18:22-23]. The phrase in this sixth verse, therefore, has the same identical meaning with each of the other three, and the marriages in reference to which it is used are those of consanguinity or too close affinity, amounting to incestuous connections.

Verse 18

Neither shalt thou take a wife to her sister, to vex her—The original is rendered in the Margin, "neither shalt thou take one wife to another to vex her," and two different and opposite interpretations have been put upon this passage. The marginal construction involves an express prohibition of polygamy; and, indeed, there can be no doubt that the practice of having more wives than one is directly contrary to the divine will. It was prohibited by the original law of marriage, and no evidence of its lawfulness under the Levitical code can be discovered, although Moses—from "the hardness of their hearts" [Mat 19:8; Mar 10:5] —tolerated it in the people of a rude and early age. The second interpretation forms the ground upon which the "vexed question" has been raised in our times respecting the lawfulness of marriage with a deceased wife's sister. Whatever arguments may be used to prove the unlawfulness or inexpediency of such a matrimonial relation, the passage under consideration cannot, on a sound basis of criticism, be enlisted in the service; for the crimes with which it is here associated warrant the conclusion that it points not to marriage with a deceased wife's sister, but with a sister in the wife's lifetime, a practice common among the ancient Egyptians, Chaldeans, and others.

Verse 21

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.

Verse 24

Defile not yourselves in any of these things—In the preceding verses seventeen express cases of incest are enumerated; comprehending eleven of affinity [Lev 18:7-16], and six of consanguinity [Lev 18:17-20], together with some criminal enormities of an aggravated and unnatural character. In such prohibitions it was necessary for the instruction of a people low in the scale of moral perception, that the enumeration should be very specific as well as minute; and then, on completing it, the divine lawgiver announces his own views of these crimes, without any exception or modification, in the remarkable terms employed in this verse.

in all these the nations are defiled which I cast out before you, &c.—Ancient history gives many appalling proofs that the enormous vices described in this chapter were very prevalent, nay, were regularly practised from religious motives in the temples of Egypt and the groves of Canaan; and it was these gigantic social disorders that occasioned the expulsion, of which the Israelites were, in the hands of a righteous and retributive Providence, the appointed instruments (Gen 15:16). The strongly figurative language of "the land itself vomiting out her inhabitants" [Lev 18:25], shows the hopeless depth of their moral corruption.

Verse 25

therefore I do visit the iniquity thereof upon it; and the land itself vomiteth out her inhabitants—The Canaanites, as enormous and incorrigible sinners, were to be exterminated; and this extermination was manifestly a judicial punishment inflicted by a ruler whose laws had been grossly and perseveringly outraged. But before a law can be disobeyed, it must have been previously in existence; and hence a law, prohibiting all the horrid crimes enumerated above—a law obligatory upon the Canaanites as well as other nations—was already known and in force before the Levitical law of incest was promulgated. Some general Iaw, then, prohibiting these crimes must have been published to mankind at a very early period of the world's history; and that law must either have been the moral law, originally written on the human heart, or a law on the institution of marriage revealed to Adam and known to the Canaanites and others by tradition or otherwise.

Verse 29

the souls that commit them shall be cut off—This strong denunciatory language is applied to all the crimes specified in the chapter without distinction: to incest as truly as to bestiality, and to the eleven cases of affinity [Lev 18:7-16], as fully as to the six of consanguinity [Lev 18:17-20]. Death is the punishment sternly denounced against all of them. No language could be more explicit or universal; none could more strongly indicate intense loathing and abhorrence.

Verse 30

Therefore shall ye keep mine ordinance, that ye commit not any one of these abominable customs—In giving the Israelites these particular institutions, God was only re-delivering the law imprinted on the natural heart of man; for there is every reason to believe that the incestuous alliances and unnatural crimes prohibited in this chapter were forbidden to all men by a law expressed or understood from the beginning of the world, or at least from the era of the flood, since God threatens to condemn and punish, in a manner so sternly severe, these atrocities in the practice of the Canaanites and their neighbors, who were not subject to the laws of the Hebrew nation.

Next: Leviticus Chapter 19
