³¹ He put another parable before them, saying, “The kingdom of heaven is like a grain of mustard seed that a man took and sowed in his field.³² It is the smallest of all seeds, but when it has grown it is larger than all the garden plants and becomes a tree, so that the birds of the air come and make nests in its branches.” ³³ He told them another parable. “The kingdom of heaven is like leaven that a woman took and hid in three measures of flour, till it was all leavened.”  ³⁴ All these things Jesus said to the crowds in parables; indeed, he said nothing to them without a parable. ³⁵ This was to fulfill what was spoken by the prophet:“I will open my mouth in parables; I will utter what has been hidden since the foundation of the world.”
