1 Corinthians 7:8-14

8But I say to the unmarried and to the widows: It is good for them if they remain even as I am;

9but if they cannot exercise self-control, let them marry. For it is better to marry than to burn with passion.

10Now to the married I command, yet not I but the Lord: A wife is not to depart from her husband.

11But even if she does depart, let her remain unmarried or be reconciled to her husband. And a husband is not to divorce his wife.

12But to the rest I, not the Lord, say: If any brother has a wife who does not believe, and she is willing to live with him, let him not divorce her.

13And a woman who has a husband who does not believe, if he is willing to live with her, let her not divorce him.

14For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband; otherwise your children would be unclean, but now they are holy.
