You will be saved from the loose woman, from the adulteress with her smooth words, who forsakes the partner of her youth and forgets her sacred covenant; for her way leads down to death, and her paths to the shades; those who go to her never come back, nor do they regain the paths of life. (NRSV 2:16-19)
To deliver thee from the strange woman, even from the stranger which flattereth with her words; which forsaketh the guide of her youth, and forgetteth the covenant of her God. For her house inclineth unto death, and her paths unto the dead. None that go unto her return again, neither take they hold of the paths of life. (KJV 2:16-19)
Don't get caught up in adultery—it's the one wrong step that causes everything else to come crashing down. Proverbs is insistent on this.
For the lips of a loose woman drip honey, and her speech is smoother than oil; but in the end she is bitter as wormwood, sharp as a two-edged sword. Her feet go down to death; her steps follow the path to Sheol. She does not keep straight to the path of life; her ways wander, and she does not know it. (NRSV 5:3-6)
For the lips of a strange woman drop as an honeycomb, and her mouth is smoother than oil: but her end is bitter as wormwood, sharp as a two-edged sword. Her feet go down to death; her steps take hold on hell. Lest thou shouldest ponder the path of life, her ways are moveable, that thou canst not know them. (KJV 5:3-6)
The superficial charms of the adulteress mask an especially bitter reality. Beware.
For the commandment is a lamp and the teaching a light, and the reproofs of discipline are the way of life, to preserve you from the wife of another, from the smooth tongue of the adulteress. Do not desire her beauty in your heart, and do not let her capture you with her eyelashes; for a prostitute's fee is only a loaf of bread, but the wife of another stalks a man's very life. Can fire be carried in the bosom without burning one's clothes? Or can one walk on hot coals without scorching the feet? So is he who sleeps with his neighbor's wife; no one who touches her will go unpunished. (NRSV 6:23-29)
For the commandment is a lamp; and the law is light; and reproofs of instruction are the way of life: to keep thee from the evil woman, from the flattery of the tongue of a strange woman. Lust not after her beauty in thine heart; neither let her take thee with her eyelids. For by means of a whorish woman a man is brought to a piece of bread: and the adultress will hunt for the precious life. Can a man take fire in his bosom, and his clothes not be burned? Can one go upon hot coals, and his feet not be burned? So he that goeth in to his neighbour's wife; whosoever toucheth her shall not be innocent. (KJV 6:23-29)
You can't manage to conceal this kind of sin or keep it under wraps—it's too highly combustible. It'll burn everything up regardless.
Then a woman comes toward him, decked out like a prostitute, wily of heart. She is loud and wayward; her feet do not stay at home; now in the street, now in the squares, and at every corner she lies in wait. She seizes him and kisses him, and with impudent face she says to him: 'I had to offer sacrifices, and today I have paid my vows; so now I have come out to meet you, to seek you eagerly, and I have found you! I have decked my couch with coverings, colored spreads of Egyptian linen; I have perfumed my bed with myrrh, aloes, and cinnamon. Come, let us take our fill of love until morning; let us delight ourselves with love. For my husband is not at home; he has gone on a long journey. He took a bag of money with him; he will not come home until full moon.' (NRSV 7:10-20)
And, behold, there met him a woman with the attire of an harlot, and subtil of heart. (She is loud and stubborn; her feet abide not in her house: now is she without, now in the streets, and lieth in wait at every corner.) So she caught him, and kissed him, and with an impudent face said unto him, I have peace offerings with me; this day have I payed my vows. Therefore came I forth to meet thee, diligently to seek thy face, and I have found thee. I have decked my bed with coverings of tapestry, with carved works, with fine linen of Egypt. I have perfumed my bed with myrrh, aloes, and cinnamon. Come, let us take our fill of love until the morning: let us solace ourselves with loves. For the goodman is not at home, he is gone a long journey: he hath taken a bag of money with him, and will come home at the day appointed. (KJV 7:10-20)
This is a cautionary example, obviously. It's also something the author witnessed looking out of the lattice of his or her house, incidentally.
Desire without knowledge is not good, and one who moves too hurriedly misses the way. (NRSV 19:2)
Also, that the soul be without knowledge, it is not good; and he that hasteth with his feet sinneth. (KJV 19:2)
If you have desires, but no knowledge, you won't know how to limit or restrain your desires in a reasonable way. Also, like coach John Wooden used to tell his players at UCLA, "Don't hurry."
This is the way of an adulteress: she eats, and wipes her mouth, and says, "I have done no wrong." (NRSV 30:20)
Such is the way of an adulterous woman; she eateth, and wipeth her mouth, and saith, I have done no wickedness. (KJV 30:20)
Adulterers treat their liaisons like they're no big thing—as casual as eating lunch.
