1 Corinthians 7:10-16

7:10 To the married I give this command – not I, but the Lord – a wife should not divorce a husband 7:11 (but if she does, let her remain unmarried, or be reconciled to her husband), and a husband should not divorce his wife.

7:12 To the rest I say – I, not the Lord – if a brother has a wife who is not a believer and she is happy to live with him, he should not divorce her. 7:13 And if a woman has a husband who is not a believer and he is happy to live with her, she should not divorce him. 7:14 For the unbelieving husband is sanctified because of the wife, and the unbelieving wife because of her husband. Otherwise your children are unclean, but now they are holy. 7:15 But if the unbeliever wants a divorce, let it take place. In these circumstances the brother or sister is not bound. God has called you in peace. 7:16 For how do you know, wife, whether you will bring your husband to salvation? Or how do you know, husband, whether you will bring your wife to salvation?
