Matthew 13:31-35

He presented another parable to them: “The kingdom of heaven is like a mustard seed that a man took and sowed in his field. It’s the smallest of all the seeds, but when grown, it’s taller than the garden plants and becomes a tree, so that the birds of the sky come and nest in its branches.” He told them another parable: “The kingdom of heaven is like leaven that a woman took and mixed into fifty pounds of flour until all of it was leavened.” Jesus told the crowds all these things in parables, and he did not tell them anything without a parable, so that what was spoken through the prophet might be fulfilled: I will open my mouth in parables; I will declare things kept secret from the foundation of the world.
