'Unmarried' in the Bible

But I say to the unmarried and to widows, it is good for them if they remain even as I am.

(but if she departs, let her remain unmarried, or else be reconciled to her husband), and that the husband not leave his wife.

But I desire to have you to be free from cares. He who is unmarried is concerned for the things of the Lord, how he may please the Lord;

There is also 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.
