Leviticus 18

Leviticus 18:1-30 . UNLAWFUL MARRIAGES.

2-4. I am the Lord your God--This renewed mention of the divine sovereignty over the Israelites was intended to bear particularly on some laws that were widely different from the social customs that obtained both in Egypt and Canaan; for the enormities, which the laws enumerated in this chapter were intended to put down, were freely practised or publicly sanctioned in both of those countries; and, indeed, the extermination of the ancient Canaanites is described as owing to the abominations with which they had polluted the land.

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 ( Luke 10:28 ) and the apostle ( Romans 10:2 ).

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" [ Leviticus 18:12-17 ], to "take" [ Leviticus 18:17 Leviticus 18:18 ], and to "lie with" [ Leviticus 18:22 Leviticus 18:23 ]. 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.

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" [ Matthew 19:8 , 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.
