'Leave' in the Bible

yet not at all meaning with the sexual sinners of this world, or with the covetous and extortioners, or with idolaters; for then you would have to leave the world.

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.

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.
