1 Corinthians 7:12

12 To the rest I say, not the Lord, that if any brother has a wife who is an unbeliever, and she consents to live with him, he should not divorce her.

1 Corinthians 7:12 In-Context

10 To the married I give charge, not I but the Lord, that the wife should not separate from her husband
11 (but if she does, let her remain single or else be reconciled to her husband) --and that the husband should not divorce his wife.
12 To the rest I say, not the Lord, that if any brother has a wife who is an unbeliever, and she consents to live with him, he should not divorce her.
13 If any woman has a husband who is an unbeliever, and he consents to live with her, she should not divorce him.
14 For the unbelieving husband is consecrated through his wife, and the unbelieving wife is consecrated through her husband. Otherwise, your children would be unclean, but as it is they are holy.
