1 Corinthians 7:12

But if they don’t have self-control, let them marry. For it’s better to marry than to burn with passion.

But to the married I command—not I, but the Lord—that the wife not leave her husband

(but if she departs, let her remain unmarried, or else be reconciled to her husband), and that the husband not leave his wife.

The woman who has an unbelieving husband, and he is content to live with her, let her not leave her husband.

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

Yet if the unbeliever departs, let there be separation. The brother or the sister is not under bondage in such cases, but God has called us in peace.
