Matthew 13:31-35

³¹He presented another parable to them, saying, “The kingdom of heaven is like a mustard seed, which a person took and sowed in his field; ³²and this is smaller than all the other seeds, but when it is fully grown, it is larger than the garden plants and becomes a tree, so that the birds of the sky come and nest in its branches.”

³³He spoke another parable to them: “The kingdom of heaven is like leaven, which a woman took and hid in three sata of flour until it was all leavened.”

³⁴All these things Jesus spoke to the crowds in parables, and He did not speak anything to them without a parable. ³⁵This was so that what was spoken through the prophet would be fulfilled:

“I will open My mouth in parables;

I will proclaim things hidden since the foundation of the world.”
