In the ancient world, parables were a teaching tool. ... Parables were fictional or illustrative stories, similar to a metaphor, and designed to teach a principle or lesson. The story of a parable often used comparison or hyperbole, and the story itself could be a model, analogy, or example of the intended lesson.
The parables of Jesus are found in the Synoptic Gospels and some of the non-canonical gospels. They form approximately one third of his recorded teachings. Christians place great emphasis on these parables, which they generally regard as the words of Jesus.
