Matthew 13:31-32 (New International Version)

The Parables of the Mustard Seed and the Yeast

 ³¹He told them another parable: "The kingdom of heaven is like a mustard seed, which a man took and planted in his field. ³²Though it is the smallest of all your seeds, yet when it grows, it is the largest of garden plants and becomes a tree, so that the birds of the air come and perch in its branches."
