Mattityahu (Mat) 13:31-35

Yeshua put before them another parable. “The Kingdom of Heaven is like a mustard seed which a man takes and sows in his field. It is the smallest of all seeds, but when it grows up it is larger than any garden plant and becomes a tree, so that the birds flying about come and nest in its branches.” And he told them yet another parable. “The Kingdom of Heaven is like yeast that a woman took and mixed with a bushel of flour, then waited until the whole batch of dough rose.” All these things Yeshua said to the crowds in parables; indeed, he said nothing to them without using a parable. This was to fulfill what had been spoken through the prophet, “I will open my mouth in parables, I will say what has been hidden since the creation of the universe.”
