1 Corinthians 7:12-14

21st Century King James Version

¹² But to the rest I speak (not the Lord): if any brother hath a wife who believeth not, and she be pleased to dwell with him, let him not put her away.

¹³ And the woman who hath a husband who believeth not, and if he be pleased to dwell with her, let her not leave him.

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