PART III. SECTION III.
EXPOSITION
MORAL UNCLEANNESS AND ITS PUNISHMENT. This being the subject of the three following chapters (chapters 18-20), they naturally form a sequence to chapters 11-17, which have dealt with ceremonial uncleanness and its purification. It is a remarkable thing that, except by implication in connection with the sin offerings and the trespass offerings and the ceremonies of the Day of Atonement, there has not yet been a single moral precept, as such, in the Book of Leviticus, and there has been very little recognition of sin as distinct from pollution. All has been ceremonial. But the ceremonial is typical of the moral, and from the consideration of ceremonial uncleanness and its remedy, we now proceed to the consideration of moral uncleanness and its penalty. It is to be noticed too that, while the ensuing laws are commanded as the positive injunction of God (verses 2, 30), which of itself is sufficient to give them their authority and force, they are still founded, like the ceremonial prohibitions, upon the feelings of repugnance implanted in the mind of man. To enter into the marriage relation with near relatives is abhorrent to a sentiment in mankind so widely spread that it may be deemed to have been originally universal, and the same abhorrence is entertained towards other foul sins of lust. Ugliness, which creates disgust by its ugliness, symbolizes sin; immorality, which inspires abhorrence by its immoral character, proves itself thereby to be sin. The section deals first with sin in the marriage relation, next with sexual impurities connected with marriage, then with other cases of immorality, and lastly with the penalties inflicted on these sins in their character of crimes.
