What the Bible says about Marriage
Rules for taking a second wife.
If he take him another wife…. – Exodus 21:10
God's rules for disposing of hated wives.
If any man take a wife, and go in unto her, and hate her, And give occasions of speech against her, and bring up an evil name upon her, and say, I took this woman, and when I came to her, I found her not a maid: Then shall the father of the damsel, and her mother, take and bring forth the tokens of the damsel's virginity unto the elders of the city in the gate…. But if this thing be true, and the tokens of virginity be not found for the damsel: Then they shall bring out the damsel to the door of her father's house, and the men of her city shall stone her with stones that she die: because she hath wrought folly in Israel, to play the whore in her father's house: so shalt thou put evil away from among you. Deuteronomy 22:13
It is better not to marry. But if you must have sex, then get married. It's better to be married than burn forever in hell.
It is good for a man not to touch a woman. Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband. 1 Corinthians 7:1-2
For I would that all men were even as I myself…. I say therefore to the unmarried and widows, It is good for them if they abide even as I. But if they cannot contain, let them marry: for it is better to marry than to burn. 1 Corinthians 7:7-9
If you're not already married, don't get married. If you have a wife, don't have sex with her. There's not enough time since Jesus is coming soon.
Art thou bound unto a wife? seek not to be loosed. Art thou loosed from a wife? seek not a wife. 1 Corinthians 7:27
But this I say, brethren, the time is short: it remaineth, that both they that have wives be as though they had none. – 1 Corinthians 7:29
