31 He proposed another parable to them, saying: "The kingdom of heaven is like a grain of mustard seed, which a man took and sowed in his field.
32 It is, indeed, the least of all seeds, but when it has grown, it is greater than all the plants, and it becomes a tree, so much so that the birds of the air come and dwell in its branches."
33 He spoke another parable to them: "The kingdom of heaven is like leaven, which a woman took and hid in three measures of fine wheat flour, until it was entirely leavened."
34 All these things Jesus spoke in parables to the crowds. And he did not speak to them apart from parables,
35 in order to fulfill what was spoken through the prophet, saying: "I will open my mouth in parables. I will proclaim what has been hidden since the foundation of the world."
