Leviticus 18:17

Thou shalt not uncover the nakedness of a woman and her daughter, neither shalt thou take her son's daughter, or her daughter's daughter, to uncover her nakedness; for they are her near kinswomen: it is wickedness.

EXPOSITORY (ENGLISH BIBLE)

Ellicott's Commentary for English Readers

(17) A woman and her daughter.—That is, if a man marries a widow who has a daughter by a former husband, or if he forms an alliance with a woman who has a daughter out of wedlock, he is forbidden to marry also the daughter. But though this prohibition is directed against a peculiar form of polygamy. there can hardly be any doubt that, as the administrators of the law during the second Temple interpreted it, if he married either of them and she died, he could not marry the other any more, and that this prohibition did not apply to cases of illicit commerce. Criminal intercourse with one did not preclude him from marrying the other. For contracting the kind of polygamy here forbidden, the offenders were punished with death by fire. (See Leviticus 20:14.)

Benson Commentary

Leviticus 18:17. A woman and her daughter — If a man married a widow that had a daughter, he was not allowed to marry this daughter, either while the mother was alive or after her death.

Matthew Henry's Concise Commentary

18:1-30 Unlawful marriages and fleshly lusts. - Here is a law against all conformity to the corrupt usages of the heathen. Also laws against incest, against brutal lusts, and barbarous idolatries; and the enforcement of these laws from the ruin of the Canaanites. God here gives moral precepts. Close and constant adherence to God's ordinances is the most effectual preservative from gross sin. The grace of God only will secure us; that grace is to be expected only in the use of the means of grace. Nor does He ever leave any to their hearts' lusts, till they have left him and his services.

Barnes' Notes on the Bible

Thy brother's wife - That is, if she had children. See Deuteronomy 25:5. The law here expressed was broken by Antipas in his connection with Herodias Matthew 14:3-4.

Jamieson-Fausset-Brown Bible Commentary

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" [Le 18:12-17], to "take" [Le 18:17, 18], and to "lie with" [Le 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.

Matthew Poole's Commentary

Of a woman and her daughter, to wit, thy step-daughter, and so thy step-son’s daughter, &c.

It is wickedness; because they are very near to thy wife by consanguinity, as coming directly from her; and therefore they are as near to thee by affinity, which binds as much as consanguinity; the wife, who is only related by affinity, being nearer to a man than any other by consanguinity, they two being made one flesh, and therefore the same distance is to be observed in both of them.

Gill's Exposition of the Entire Bible

Thou shall not uncover the nakedness of a woman and her daughter,.... That is, if a man marries a woman, and she has a daughter, which is the man's daughter-in-law, after the death of his wife he may not marry this daughter; for this daughter is of the same flesh with her mother, who became one flesh with the man she married, and therefore his relation to her daughter is too near to marry her: Jarchi says, if he does not marry the woman, but only deflower her, it is free for him to marry her daughter; but Aben Ezra says, if he has lain with the mother, the daughter is forbidden; however, if he married either of them, the other was forbidden; he could not marry them both, neither in the lifetime of them both, nor after the death of either of them:

neither shalt thou take her son's daughter, or her daughter's daughter, to uncover her nakedness; not any of her granddaughters, either in the line of her son or daughter; that is, might not lie with either of them, or marry them, and much less then marry her own daughter, these being a further remove from her:

for they are her near kinswomen; one or other of them, even every one of them, "the rest" and residue "of her" (r), of her flesh, who together made one flesh with her; and therefore not to be married to her husband, either in her life, or after her death:

it is wickedness: a very great wickedness, abominable in the sight of God, and to be detested by man as vile and impious; it is whoredom, as the Targum of Jonathan renders it.

(r) "reliquiae sunt ipsae", Tigurine version.

Geneva Study Bible

Thou shalt not uncover the nakedness of a woman and her daughter, neither shalt thou take her son's daughter, or her daughter's daughter, to uncover her nakedness; for they are her near kinswomen: it is wickedness.

EXEGETICAL (ORIGINAL LANGUAGES)

Pulpit Commentary

Verse 17. - The ninth form of incest prohibited is intercourse with a stepdaughter, or step-granddaughter, or mother-in-law. The expression made use of, Thou shalt not uncover the nakedness of a woman and her daughter, covers the case of a man's own daughter, and it is singular that it is only in this incidental manner that it is specifically named. But it has been already disposed of by the general command, None of you shall approach to any that is near of kin to him, to uncover their nakedness. The daughter being nearest of kin, this command was sufficient without further specification. The niece and probably the wife's sister are forbidden by the same general rule (see following note). Leviticus 18:17

Keil and Delitzsch Biblical Commentary on the Old Testament

Marriage with a woman and her daughter, whether both together or in succession, is described in Deuteronomy 27:20 as an accursed lying with the mother-in-law; whereas here it is the relation to the step-daughter which is primarily referred to, as we may see from the parallel prohibition, which is added, against taking the daughter of her son or daughter, i.e., the granddaughter-in-law. Both of these were crimes against blood-relationship which were to be punished with death in the case of both parties (Leviticus 20:14), because they were "wickedness," זמּה, lit., invention, design, here applied to the crime of licentiousness and whoredom (Leviticus 19:29; Judges 20:6; Job 31:11).
