1 Corinthians 7:12-14

New King James Version

¹² But 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. ¹³ And a woman who has a husband who does not believe, if he is willing to live with her, let her not divorce him. ¹⁴ For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband; otherwise ^(A)your children would be unclean, but now they are holy.
