31 Jesus told them another parable: "The Kingdom of heaven is like this. A man takes a mustard seed and sows it in his field. 32 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."
The Parable of the Yeast
34 Jesus used parables to tell all these things to the crowds; he would not say a thing to them without using a parable.
