"19 Also thou shalt not approach unto a woman to uncover her nakedness, as long as she is put apart for her uncleanness. 20 Moreover thou shalt not lie carnally with thy neighbour’s wife, to defile thyself with her. 21 And thou shalt not let any of thy seed pass through the fire to Molech, neither shalt thou profane the name of thy God: I am the LORD. 22 Thou shalt not lie with mankind, as with womankind: it is abomination. 23 Neither shalt thou lie with any beast to defile thyself therewith: neither shall any woman stand before a beast to lie down thereto: it is confusion. 24 Defile not ye yourselves in any of these things: for in all these the nations are defiled which I cast out before you: 25 And the land is defiled: therefore I do visit the iniquity thereof upon it, and the land itself vomiteth out her inhabitants. 26 Ye shall therefore keep my statutes and my judgments, and shall not commit any of these abominations; neither any of your own nation, nor any stranger that sojourneth among you: 27 (For all these abominations have the men of the land done, which were before you, and the land is defiled;) 28 That the land spue not you out also, when ye defile it, as it spued out the nations that were before you. 29 For whosoever shall commit any of these abominations, even the souls that commit them shall be cut off from among their people. 30 Therefore shall ye keep mine ordinance, that ye commit not any one of these abominable customs, which were committed before you, and that ye defile not yourselves therein: I am the LORD your God." — Leviticus 18:19 KJV.
19. Thou shalt not approach — This verse forbids contracting the ceremonial impurity specified in Leviticus 15:19, 25. See notes. In Leviticus 20:18, the penalty of death is denounced against both parties to the offence. See note.
20. Thy neighbour’s wife — This is a repetition of the seventh commandment, in another form, for the purpose of emphasis and of completing the enumeration of abominations prevalent in Egypt and Canaan. This verse prohibits not only adultery proper, or double adultery, as some laws define this crime, in two married persons, (see Exodus 20:14, note,) but also one species of single adultery. Defile thyself — This is moral and ceremonial pollution.
