'Married' in the Bible

To the married I command--not I, but the Lord--a wife must not separate from [her] husband.

But the one who is married cares for the things of the world, how he may please his wife,

and he is divided. And the unmarried woman or the virgin cares for the things of the Lord, in order that she may be holy both in body and in spirit. But the married woman cares for the things of the world, how she may please her husband.
