1 Corinthians 7:10

Yet I wish that all men were like me. However, each man has his own gift from God, one of this kind, and another of that kind.

But I say to the unmarried and to widows, it is good for them if they remain even as I am.

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

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

But to the rest I—not the Lord—say, if any brother has an unbelieving wife, and she is content to live with him, let him not leave her.

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