³¹He put before them another parable: “The kingdom of heaven is like a mustard seed that someone took and sowed in his field; ³²it is the smallest of all the seeds, but when it has grown it is the greatest of shrubs and becomes a tree, so that the birds of the air come and make nests in its branches.” ³³He told them another parable: “The kingdom of heaven is like yeast that a woman took and mixed in with three measures of flour until all of it was leavened.” ³⁴Jesus told the crowds all these things in parables; without a parable he told them nothing. ³⁵This was to fulfill what had been spoken through the prophet: “I will open my mouth to speak in parables; I will proclaim what has been hidden from the foundation of the world.”
