Adultery
Marriage is a scared institution in the eyes of God'
Leviticus 20:12 "And the man that commits adultery with another man's wife, even he that commits adultery with his neighbor's wife, the adulterer and the adulteress shall surely be put to death. And the man that lieth with his father's wife hath uncovered his father's nakedness: both of them shall surely be put to death; their blood shall be upon them. And if a man lie with his daughter in law, both of them shall surely be put to death: they have wrought confusion; their blood shall be upon them."
The seriousness of this issue is revealed in that the punishment for it was a death
sentence.
Leviticus 20:20-21 " And if a man shall lie with his uncle's wife, he hath uncovered his uncle's nakedness [The term nakedness refers to having sex]: they shall bear their sin; they shall die childless. And if a man shall take his brother's wife, it is an unclean thing: he hath uncovered his brother's nakedness; they shall be childless."
Deuteronomy 22:30 "A man shall not take his father's wife, nor discover his father's skirt."
Luke 16:18 "Whosoever putts away his wife, and marries another, commits adultery: and whosoever married her that is put away from her husband commits adultery."
Matthew 19:3-12 " The Pharisees also came unto him, tempting him, and saying unto him, Is it lawful for a man to put away his wife for every cause? And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female, And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh? Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder. They say unto him, Why did Moses then command to give a writing of divorcement, and to put her away? He saith unto them, Moses because of the hardness of your hearts suffered you to put away your wives: but from the beginning it was not so. And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, commits adultery: and whoso married her which is put away doth commit adultery. His disciples say unto him, If the case of the man be so with his wife, it is not good to marry. But he said unto them, All men cannot receive this saying, save they to whom it is given. For there are some eunuchs, which were so born from their mother's womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven's sake. He that is able to receive it, let him receive it."
Mark 10:4-12 " And the Pharisees came to him, and asked him, Is it lawful for a man to put away his wife? tempting him. And he answered and said unto them, What did Moses command you? And they said, Moses suffered to write a bill of divorcement, and to put her away. And Jesus answered and said unto them, For the hardness of your heart he wrote you this precept. But from the beginning of the creation God made them male and female. For this cause shall a man leave his father and mother, and cleave to his wife; And they twain shall be one flesh: so then they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder. And in the house his disciples asked him again of the same matter. And he saith unto them, Whosoever shall put away his wife, and marry another, commits adultery against her. And if a woman shall put away her husband, and be married to another, she commits adultery."
Proverbs 6:20-35 "My son, keep thy father's commandment, and forsake not the law of thy mother: Bind them continually upon thine heart, and tie them about thy neck. When thou goest, it shall lead thee; when thou sleepest, it shall keep thee; and when thou awakest, it shall talk with thee. 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 adulteress 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. Men do not despise a thief, if he steal to satisfy his soul when he is hungry; But if he be found, he shall restore sevenfold; he shall give all the substance of his house. But whoso committeth adultery with a woman lacketh understanding: he that doeth it destroyeth his own soul. A wound and dishonour shall he get; and his reproach shall not be wiped away. For jealousy is the rage of a man: therefore he will not spare in the day of vengeance. He will not regard any ransom; neither will he rest content, though thou givest many gifts."
As far as prostitution is concerned:
Proverbs 7:5-27 "That they may keep thee from the strange woman, from the stranger which flattereth with her words. For at the window of my house I looked through my casement, And beheld among the simple ones, I discerned among the youths, a young man void of understanding, Passing through the street near her corner; and he went the way to her house, In the twilight, in the evening, in the black and dark night: 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. With her much fair speech she caused him to yield, with the flattering of her lips she forced him. He goeth after her straightway, as an ox goeth to the slaughter, or as a fool to the correction of the stocks; Till a dart strike through his liver; as a bird hasteth to the snare, and knoweth not that it is for his life. Hearken unto me now therefore, O ye children, and attend to the words of my mouth. Let not thine heart decline to her ways, go not astray in her paths. For she hath cast down many wounded: yea, many strong men have been slain by her. Her house is the way to hell, going down to the chambers of death."
Proverbs 9:13-18 "A foolish woman is clamorous: she is simple, and knoweth nothing. For she sitteth at the door of her house, on a seat in the high places of the city, To call passengers who go right on their ways: Whoso is simple, let him turn in hither: and as for him that wanteth understanding, she saith to him, Stolen waters are sweet, and bread eaten in secret is pleasant. But he knoweth not that the dead are there; and that her guests are in the depths of hell."
