But because of sexual immorality, each man should have his own wife, and each woman should have her own husband.
References for 1 Corinthians 7:2

A wife does not have authority over her own body, but her husband does. Equally, a husband does not have authority over his own body, but his wife does.
Do not deprive one another-except when you agree, for a time, to devote yourselves to prayer. Then come together again; otherwise, Satan may tempt you because of your lack of self-control.

But to the rest I, not the Lord, say: If any brother has an unbelieving wife, and she is willing to live with him, he must not leave her.
Also, if any woman has an unbelieving husband, and he is willing to live with her, she must not leave her husband.
For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the Christian husband. Otherwise your children would be unclean, but now they are holy.
But if the unbeliever leaves, let him leave. A brother or a sister is not bound in such cases. God has called you to peace.

And I say this, brothers: the time is limited, so from now on those who have wives should be as though they had none,
those who weep as though they did not weep, those who rejoice as though they did not rejoice, those who buy as though they did not possess,
and those who use the world as though they did not make full use of it. For this world in its current form is passing away.
I want you to be without concerns. An unmarried man is concerned about the things of the Lord-how he may please the Lord.
But a married man is concerned about the things of the world-how he may please his wife-
and he is divided. An unmarried woman or a virgin is concerned about the things of the Lord, so that she may be holy both in body and in spirit. But a married woman is concerned about the things of the world-how she may please her husband.
Now I am saying this for your own benefit, not to put a restraint on you, but because of what is proper, and so that you may be devoted to the Lord without distraction.

A wife is bound as long as her husband is living. But if her husband dies, she is free to be married to anyone she wants-only in the Lord.
References for 1 Corinthians 7:39
But she is happier if she remains as she is, in my opinion. And I think that I also have the Spirit of God.
