1 Corinthians 7:12-14

Revised Geneva Translation

¹² Now, to the rest I speak (I, not the Lord). If any brother has a wife who does not believe, if she is content to dwell with him, let him not leave her.

¹³ And the woman who has a husband who does not believe, if he is content to dwell with her, let her not leave him.

¹⁴ For the unbelieving husband is sanctified in the wife, and the unbelieving wife is sanctified in the husband, or else your children would be unclean. But now they are holy.
