1 Corinthians 7:12
King James Version
“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.”
Context
9But if they cannot contain, let them marry: for it is better to marry than to burn.
10And unto the married I command, not I, but the Lord, Let not the wife depart from husband:
11But and if she depart, let her remain unmarried, or be reconciled to husband: and let not the husband put away wife.
12But 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.
13And the woman which hath an husband that believeth not, and if he be pleased to dwell with her, let her not leave him.
14For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband: else were your children unclean; but now are they holy.
15But if the unbelieving depart, let him depart. A brother or a sister is not under bondage in such but God hath called us to peace.
