Matthew 13:31-35

Jesus told them another parable: “The Kingdom of heaven is like this. A man takes a mustard seed and sows it in his field. It is the smallest of all seeds, but when it grows up, it is the biggest of all plants. It becomes a tree, so that birds come and make their nests in its branches.” Jesus told them still another parable: “The Kingdom of heaven is like this. A woman takes some yeast and mixes it with a bushel of flour until the whole batch of dough rises.” Jesus used parables to tell all these things to the crowds; he would not say a thing to them without using a parable. He did this to make come true what the prophet had said, “I will use parables when I speak to them; I will tell them things unknown since the creation of the world.”
