Parable of the Leaven
The Parable of the Leaven (also called the Parable of the Yeast) is one of the shorter parables of Jesus.
It appears in two of the Canonical gospels of the New Testament. The differences between Gospels of Matthew 13:33 & Luke 13:20–21 are minor.
(He told them still another parable: “The kingdom of heaven is like yeast that a woman took and mixed into about sixty pounds of flour until it worked all through the dough.”) Matthew 13:33
Its theme is that of the Kingdom of Heaven growing from small beginnings. The final outcome is inevitable once the natural process of growth has begun.
Matthew 13:33
