A husband accused his newlywed wife in Deuteronomy 22:
If a man has sex with a married woman:
In the NT, premarital sex is under the general umbrella of sexual immorality, 1 Corinthians 6:
If a woman had premarital sex and her new husband complained about it, she could be stoned to death.20 If, however, the charge is true and no proof of the young woman’s virginity can be found, 21 she shall be brought to the door of her father’s house and there the men of her town shall stone her to death. She has done an outrageous thing in Israel by being promiscuous while still in her father’s house. You must purge the evil from among you.
If a man has sex with a married woman:
If a man has sex with an unmarried woman, Exodus 22:22 “If a man is found lying with the wife of another man, both of them shall die, the man who lay with the woman, and the woman. So you shall purge the evil from Israel.
In the OT, there was a double standard due to polygyny.16 “If a man seduces a virgin who is not pledged to be married and sleeps with her, he must pay the bride-price, and she shall be his wife. 17 If her father absolutely refuses to give her to him, he must still pay the bride-price for virgins.
In the NT, premarital sex is under the general umbrella of sexual immorality, 1 Corinthians 6:
Legal sex is described in 1 Corinthians 7:18-20 Flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body. Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, for you were bought with a price. So glorify God in your body.
Today, in Canada where I live, polygyny is a crime and marrying a non-virgin woman is not. So we cannot apply these OT laws in Canada. In any case, Jesus fulfilled the Law already. There is no need to be legalistic about it. My point is a spiritual one: sex outside of a husband and wife relationship is sin, then and now, in the eyes of God.2 But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband.
