12 To the rest I say—I, not the Lord—if a brother has a wife who is not a believer and she is happy to live with him, he should not divorce her.
Darby
12 But as to the rest, *I* say, not the Lord, If any brother have an unbelieving wife, and *she* consent to dwell with him, let him not leave her.
KJV
12 But to the rest speak I, not the Lord: If any brother hath a wife that believeth not, and she be pleased to dwell with him, let him not put her away.
