I Corinthians 7:28, 32-34, 38

But even if you do marry, you have not sinned; and if a virgin marries, she has not sinned. Nevertheless such will have trouble in the flesh, but I would spare you.

But I want you to be without care. He who is unmarried cares for the things of the Lord—how he may please the Lord. But he who is married cares about the things of the world—how he may please his wife. There is a difference between a wife and a virgin. The unmarried woman cares about the things of the Lord, that she may be holy both in body and in spirit. But she who is married cares about the things of the world—how she may please her husband.

So then he who gives her in marriage does well, but he who does not give her in marriage does better.
