31He set another parable before them, saying: The kingdom of the heavens is like a mustard seed, which a man took and sowed in his field.32It is smaller than all the seeds on the one hand; but when it is grown it is greater than the plants and becomes a tree, so that the birds of the heaven come and dwell in its branches.33He spoke another parable to them: The kingdom of the heavens is like leaven, which a woman took and mixed into three seahs of flour until all was leavened.34Jesus spoke all these things to the crowds in parables, and without a parable he spoke nothing to them.35This was to fulfill what was spoken through the prophet, who said: I will open my mouth in parables; I will utter things hidden from the beginning.
