Левит 18:6

The laws against incest are introduced in Lev 18:6 with the general prohibition, descriptive of the nature of this sin, "None of you shall approach בּשׂרו אל־כּל־שׁאר to any flesh of his flesh, to uncover nakedness." The difference between שׁאר flesh, and בּשׂר flesh, is involved in obscurity, as both words are used in connection with edible flesh (see the Lexicons). "Flesh of his flesh" is a flesh that is of his own flesh, belongs to the same flesh as himself (Gen 2:24), and is applied to a blood-relation, blood-relationship being called שׁארה (or flesh-kindred) in Hebrew (Lev 18:17). Sexual intercourse is called uncovering the nakedness of another (Eze 16:36; Eze 23:18). The prohibition relates to both married and unmarried intercourse, though the reference is chiefly to the former (see Lev 18:18; Lev 20:14, Lev 20:17, Lev 20:21). Intercourse is forbidden (1) with a mother, (2) with a step-mother, (3) with a sister or half-sister, (4) with a granddaughter, the daughter of either son or daughter, (5) with the daughter of a step-mother, (6) with an aunt, the sister of either father or mother, (7) with the wife of an uncle on the father's side, (8) with a daughter-in-law, (9) with a sister-in-law, or brother's wife, (10) with a woman and her daughter, or a woman and her granddaughter, and (11) with two sisters at the same time. No special reference is made to sexual intercourse with (a) a daughter, (b) a full sister, (c) a mother-in-law; the last, however, which is mentioned in Deu 27:23 as an accursed crime, is included here in No. 10, and the second in No. 3, whilst the first, like parricide in Exo 21:15, is not expressly noticed, simply because the crime was regarded as one that never could occur. Those mentioned under Nos. 1, 2, 3, 8, and 10 were to be followed by th…

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 a…
