Matthew 13:31-32 - The Parable Of The Mustard Seed
31 He delivered them another parable, saying, The kingdom of heaven is like a mustard seed which a man took and sowed in his field, 32 which is the least of all seeds, but when it is grown is the greatest of plants, and becomes a tree, so that the birds of heaven come and lodge on its branches.
30 And he said, To what shall I liken the kingdom of God? or with what parable shall I present it? 31 It is like a mustard seed, which when sown in the earth is the least of all seeds on the earth; 32 but when sown, it comes up, and becomes the greatest of all plants, and produces great branches, so that the birds of heaven can dwell under its shade.
33 And with many such parables spoke he the word to them as they could hear; 34 but without a parable spoke he not to them; and, privately, he explained all things to his disciples.
