1 Corinthians 7:8-14

8But I say to the unmarried and to the widows, It is good for them that they remain even as I.

9But if they have not control over themselves, let them marry; for it is better to marry than to burn.

10But to the married I enjoin, not I, but the Lord, Let not wife be separated from husband;

11(but if also she shall have been separated, let her remain unmarried, or be reconciled to her husband;) and let not husband leave wife.

12But 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.

13And a woman who has an unbelieving husband, and he consents to dwell with her, let her not leave [her] husband.

14For the unbelieving husband is sanctified in the wife, and the unbelieving wife is sanctified in the brother; since [otherwise] indeed your children are unclean, but now they are holy.
