'Marriage' in the Bible

I now deal with the subjects mentioned in your letter. It is well for a man to abstain altogether from marriage.

If, however, they cannot maintain self-control, by all means let them marry; for marriage is better than the fever of passion.

The one bound to a wife should not seek divorce. The one released from a wife should not seek marriage.

So then he that giveth her in marriage doeth well; but he that giveth her not in marriage doeth better.
