| Clarke's Commentary on the Bible Committeth adultery - To what has been said in the note on See Exodus 20:14 (note), we may add, that the word adultery comes from the Latin adulterium, which is compounded of ad, to or with, and alter, another, or, according to Minshieu, of ad alterius forum, he that approaches to another man's bed.
Gill's Exposition of the Entire BibleAnd the man that committeth adultery with another man's wife,.... Which is a breach of the seventh command, Exodus 20:14, even he that committeth adultery with his neighbour's wife: which is only an explanation of the former clause; though the Jewish writers, as Jarchi and Ben Gersom, say this is so expressed to except the wife of a stranger, or a Gentile; but it means whether a Gentile or an Israelite; and which may be confirmed by the instance of Phinehas slaying a prince of Israel, that lay with a Midianitish woman, Numbers 25:6, the adulterer and the adulteress shall surely be put to death; on account of her that is espoused, by strangling, with a hard napkin within a soft one; and on account of her that is married, by casting stones; even both the adulterer and adulteress, as the Targum: and the Jews say (b), strangling was thus performed; they that were strangled were fixed up to their knees in dung, and then they put a hard napkin within a soft one, and rolled it about his neck, and one drew it to him this way, and another drew it to him that way, until he expired: and there is no unlawful copulation punished with strangling, according to Maimonides (c), but lying with another man's wife; and who observes, that the death which is spoken of in the law absolutely, that is, without specifying any kind of death, is strangling; but stoning seems rather meant, agreeably to Deuteronomy 22:24. (b) Misn. Sanhedrin, c. 7. sect. 3.((c) Hilchot lssure Biah, c. 1. sect. 6.
Geneva Study BibleAnd the man that committeth adultery with another man's wife, even he that committeth adultery with his neighbor's wife, the adulterer and the adulteress shall surely be put to death.
Matthew Henry's Concise Commentary20:10-27 These verses repeat what had been said before, but it was needful there should be line upon line. What praises we owe to God that he has taught the evil of sin, and the sure way of deliverance from it! May we have grace to adorn the doctrine of God our Saviour in all things; may we have no fellowship with unfruitful works of darkness, but reprove them.
Matthew Henry's Whole Bible CommentaryVerses 10-21 Sins against the seventh commandment are here ordered to be severely punished. These are sins which, of all others, fools are most apt to make a mock at; but God would teach those the heinousness of the guilt by the extremity of the punishment that would not otherwise be taught it. I. Lying with another man's wife was made a capital crime. The adulterer and the adulteress that had joined in the sin must fall alike under the sentence: they shall both be put to death, v. 10. Long before this, even in Job's time, this was reputed a heinous crime and an iniquity to be punished by the judges, Job 31:11. It is a presumptuous contempt of an ordinance of God, and a violation of his covenant, Prov. 2:17. It is an irreparable wrong to the injured husband, and debauches the mind and conscience of both the offenders as much as any thing. It is a sin which headstrong and unbridled lusts hurry men violently to, and therefore it needs such a powerful restraint as this. It is a sin which defiles a land and brings down God's judgments upon it, which disquiets families, and tends to the ruin of all virtue and religion, and therefore is fit to be animadverted upon by the conservators of the public peace: but see Jn. 8:3-11. II. Incestuous connections, whether by marriage or not. 1. Some of them were to be punished with death, as a man's lying with his father's wife, v. 11. Reuben would have been put to death for his crime (Gen. 35:22) if this law had been then made. It was the sin of the incestuous Corinthian, for which he was to be delivered unto Satan, 1 Co. 5:1, 5. A man's debauching his daughter-in-law, or his mother-in-law, or his sister, was likewise to be punished with death, v. 12, 14, 17. 2. Others of them God would punish with the curse of barrenness, as a man's defiling his aunt, or his brother's wife (v. 19-21): They shall die childless. Those that keep not within the divine rules of marriage forfeit the blessings of marriage: They shall commit whoredom, and shall not increase, Hos. 4:10. Nay it is said, They shall bear their iniquity, that is, though they be not immediately cut off by the hand either of God or man for this sin, yet the guilt of it shall lie upon them, to be reckoned for another day, and not be purged with sacrifice or offering. III. The unnatural lusts of sodomy and bestiality (sins not to be mentioned without horror) were to be punished with death, as they are at this day by our law, v. 13, 15, 16. Even the beast that was thus abused was to be killed with the sinner, who was thereby openly put to the greater shame: and the villany was thus represented as in the highest degree execrable and abominable, all occasions of the remembrance or mention of it being to be taken away. Even the unseasonable use of the marriage, if presumptuous, and in contempt of the law, would expose the offenders to the just judgment of God: they shall be cut off, v. 18. For this is the will of God, that every man should possess his vessel (and the wife is called the weaker vessel) in sanctification and honour, as becomes saints. |
