And a wife who has an unbelieving husband, if he consents to live with her, let her not divorce him.
And if a wife should put away her husband and be married to another, she commits adultery."
But to the rest I, not the Lord, say: If any brother has an unbelieving wife, and she consents to live with him, let him not divorce her.
For the unbelieving husband has been sanctified by the wife, and the unbelieving wife has been sanctified by the husband; otherwise your children would be unclean, but now they are holy.
