Proverbs 6:26 is very interesting. It is translated in various ways in different translations, some of which don't seem to make much logical sense. But the NRSV renders it extremely interestingly:
Proverbs 6:23-35
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;
26) 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 neighbour's wife; no one who touches her will go unpunished. Thieves are not despised who steal only to satisfy their appetite when they are hungry. Yet if they are caught, they will pay sevenfold; they will forfeit all the goods of their house. But he who commits adultery has no sense; he who does it destroys himself. He will get wounds and dishonour, and his disgrace will not be wiped away. For jealousy arouses a husband's fury, and he shows no restraint when he takes revenge. He will accept no compensation, and refuses a bribe no matter how great.
The proverbs introduce the strange woman in chapter 2.
Pro 2:16 To deliver thee from the strange woman, even from the stranger which flattereth with her words;
It then picks it back up in chapter 5 and then delves deeper into the topic of adultery here in chapter 6. It continues on though in chapter 7 and reveals that this strange woman is indeed married. She is seeking to devour him through adultery.
Pro 7:5 That they may keep thee from the
strange woman, from
the stranger which flattereth with her words.
Pro 7:6 For at the window of my house I looked through my casement,
Pro 7:7 And beheld among the simple ones, I discerned among the youths, a young man void of understanding,
Pro 7:8 Passing through the street near her corner; and he went the way to her house,
Pro 7:9 In the twilight, in the evening, in the black and dark night:
Pro 7:10 And, behold, there met him a woman with the
attire of an harlot, and subtil of heart.
Pro 7:11 (She is loud and stubborn; her feet abide not in her house:
Pro 7:12 Now is she without, now in the streets, and lieth in wait at every corner.)
Pro 7:13 So she caught him, and kissed him, and with an impudent face said unto him,
Pro 7:14 I have peace offerings with me; this day have I payed my vows.
Pro 7:15 Therefore came I forth to meet thee, diligently to seek thy face, and I have found thee.
Pro 7:16 I have decked my bed with coverings of tapestry, with carved works, with fine linen of Egypt.
Pro 7:17 I have perfumed my bed with myrrh, aloes, and cinnamon.
Pro 7:18 Come, let us take our fill of love until the morning: let us solace ourselves with loves.
Pro 7:19
For the goodman is not at home, he is gone a long journey:
Pro 7:20 He hath taken a bag of money with him, and will come home at the day appointed.
There is GREAT danger in taking a woman whom you do not know, whose history you do not know, whose current status you do not know.
A Strange woman will tell you all that you want to hear in order to get what she wants from you. You should do your due diligence to find out from those that know her, what her true history and status is or you could be caught in adultery without intending it.
I do not think that it is a sin to be with an unmarried prostitute. But as this passage reveals, a married woman may meet you with the attire of a prostitute and cause you to fall into sin.
The wisdom then is to avoid prostitutes altogether so that you avoid this trap.
We see that instruction in chapter 5.
Pro 5:15
Drink waters out of thine own cistern, and running waters out of thine own well.
Pro 5:16 Let thy fountains be dispersed abroad, and rivers of waters in the streets.
Pro 5:17
Let them be only thine own, and not strangers' with thee.
Pro 5:18 Let thy fountain be blessed: and
rejoice with the wife of thy youth.
Pro 5:19 Let her be as the loving hind and pleasant roe; let her breasts satisfy thee at all times; and be thou ravished always with her love.
Pro 5:20
And why wilt thou, my son, be ravished with a strange woman, and embrace the bosom of
a stranger?
This is my take away from the beginning of Psalms...
