1. Korinther 7:34

welche nicht freit, die sorgt, was dem HERRN angehört, daß sie heilig sei am Leib und auch am Geist; die aber freit, die sorgt, was der Welt angehört, wie sie dem Manne gefalle.

There is difference also between a wife and a virgin. The unmarried woman careth for the things of the Lord, that she may be holy both in body and in spirit: but she that is married careth for the things of the world, how she may please her husband.
