Matthew 13:31-34

Then Jesus taught them another parable: “Heaven’s kingdom can be compared to the tiny mustard seed that a man takes and plants in his field. Although the smallest of all the seeds, it eventually grows into the greatest of garden plants, becoming a tree for birds to come and build their nests in its branches.” Then he taught them another parable: “Heaven’s kingdom can be compared to yeast that a woman takes and blends into three measures of flour and then waits until all the dough rises.” Whenever Jesus addressed the crowds, he always spoke in allegories. He never spoke without using parables.
