Parables of Jesus
A number of parables which are adjacent in one or more gospels have similar themes. The parable of the Leaven follows the parable of the Mustard Seed in  Matthew and Luke, and shares the theme of the Kingdom of Heaven growing from small beginnings. The parable of the Hidden Treasure and parable of the Pearl form a pair illustrating the great value of the Kingdom of Heaven, and the need for action in attaining it.
