Parable: speaking in a figurative poetic style, Numbers xxiii. 7. Job grants that God generally punishes the wicked, but he maintains that he also chastises the just; and hence admonishes all to revere his judgments and wisdom, and to decline from evil; which truths must always subsist, whatever may be the conduct of Providence. (Calmet)
Parables do not always imply similies, but sometimes pithy, and profound sentences, spoken by the wisest men.
