'Depart' in the Bible

But unto the married I give charge, yea not I, but the Lord, That the wife depart not from her husband

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

Yet if the unbelieving departeth, let him depart: the brother or the sister is not under bondage in such cases : but God hath called us in peace.
